[Test] All Fours × Cleavage Prompt Comparison — Effects of cleavage, from above, and crawling

Conclusion

For showing cleavage in an all fours pose, using from above, looking up at viewer to create an overhead angle (Condition E) was the most stable approach. cleavage alone makes cleavage more likely, but the pose tends to shift to a kneeling-forward-lean instead of true all fours. hanging breasts strongly tends to cause costume disappearance into nudity and is difficult to control.

What You’ll Learn from This Article

• all fours alone has a low reproduction rate for the all fours pose
• Adding cleavage shows cleavage but tends to change the pose to a kneeling-forward-lean
• from above, looking up at viewer for an overhead angle stabilizes the all fours + cleavage composition
• hanging breasts has a high risk of inducing nudity
• crawling produces a different pose from all fours (a lower, more horizontal crawling posture)
• Costume specification (white tank top or low-cut top) stabilizes how cleavage appears

Experiment Conditions

Base Prompt

Elements common to all conditions:

1girl, 32yo japanese actress, [pose/cleavage spec], looking at viewer, on bed, indoor, soft lighting

Some conditions change looking at viewer to looking up at viewer.

Condition A: Baseline (No Cleavage Specification)

NSFW - クリックで表示

Observations

• 0 out of 3 images showed a clear all fours pose
• seed42: Striped shirt with denim shorts, sitting pose. No cleavage visible
• seed123: Seated on sofa in tank top. Chest barely visible
• seed789: Collage composition (multiple cuts combined). Lingerie with near-all-fours or prone poses
• all fours alone tends to produce sitting or kneeling poses; low reproduction rate for true all fours

Condition B: Adding cleavage

NSFW - クリックで表示

Observations

• 3 out of 3 images showed cleavage (clear difference from Condition A)
• seed42: White bikini, kneeling-forward-lean. Cleavage clearly visible
• seed123: On sofa in navy outfit, leaning forward with cleavage
• seed789: Collage composition, but both cuts show near-all-fours in black bra with clear cleavage
• Adding cleavage tends to shift costume toward more revealing (bikini/bra)
• Pose is mostly kneeling-forward-lean; only 1 of 3 (seed789) showed a fully all fours pose

Condition C: deep cleavage + low-cut top

NSFW - クリックで表示

Observations

• 3 out of 3 images showed deep cleavage
• seed42: Gray V-neck knit with deep cleavage. Kneeling-forward-lean pose
• seed123: Navy lace camisole with cleavage. Kneeling-forward-lean
• seed789: White bikini in all fours pose with clear deep cleavage. However, artifact with triple-rendered figure
• low-cut top tends to produce costume designs with a widely-open neckline
• deep cleavage tends to show deeper cleavage than cleavage

Condition D: hanging breasts

NSFW - クリックで表示

Observations

• 2 out of 3 images went topless (no costume)
• seed42: V-neck cardigan while sitting. Cleavage visible but costume present
• seed123: Topless with multiple-figure artifact. Pendant breast depiction
• seed789: Topless while sitting. Large pendulous breasts depicted
• hanging breasts strongly tends to eliminate costume and induce nudity
• If you want cleavage with costume, hanging breasts is not suitable

Condition E: from above (slightly overhead angle)

NSFW - クリックで表示

Observations

• 3 out of 3 images reproduced the overhead angle with clearly visible cleavage
• seed42: Overhead with near-all-fours pose, white bra with clear cleavage
• seed123: Overhead with forward-lean pose, black bra with cleavage
• seed789: Overhead with legs-spread forward-lean, black bra with cleavage
• from above stably controls the angle; looking up at viewer also directs gaze forward
• The overhead angle structurally makes the chest area visible; most stable condition for cleavage

Lab Director comment: Oh wow, all 3 are hits. An overhead view with an upward gaze, and you can see a ton of cleavage — this is great. Filing away the from above + looking up at viewer combination.

Condition F: crawling

NSFW - クリックで表示

Observations

• 3 out of 3 images reproduced the crawling pose
• seed42: Bikini in crawling pose, diagonal angle shows side-to-cleavage area
• seed123: Camisole in crawling pose, slight cleavage
• seed789: Near-topless in crawling pose, breasts visible from side
• crawling produces a different pose from all fours — lower body, more horizontal
• The composition tends to be diagonal-to-side rather than frontal, making frontal cleavage less stable than Conditions B/E

Condition G: white tank top + cleavage (costume-guided cleavage)

NSFW - クリックで表示

Observations

• 3 out of 3 images reproduced the white tank top with cleavage visible
• seed42: White tank top, kneeling-forward-lean, cleavage clearly visible through scoop neck
• seed123: White tank top while sitting, with cleavage
• seed789: Collage 4-panel composition. White tank top in all fours to prone pose, with cleavage
• Specific costume specification stabilizes costume reproduction and how cleavage appears
• More controllable than Condition D since nudity is avoided while showing cleavage

Condition H: Combined (Everything)

NSFW - クリックで表示

Observations

• 3 out of 3 images showed overhead angle + cleavage
• seed42: Overhead, gray sports bra, kneeling-forward-lean, deep cleavage
• seed123: Overhead, navy bra, kneeling-forward-lean, with cleavage
• seed789: Overhead, topless in all fours. hanging breasts reproduced and costume disappeared
• from above dominates angle control as with Condition E
• When hanging breasts and low-cut top compete, costume tends to disappear (1 of 3 images)
• Overloading the prompt increases risks of unintended elements (nudity, artifacts)

Lab Director Comment

So, what we found out is that from above is key for angle control. The all fours pose reproduction rate was generally low overall, but if we can get cleavage stably with the overhead angle, that’s practically enough. hanging breasts causes nudity and makes the prompt go wild, so if you’re going for costumed shots, I’d say avoid it.

Key Findings

1. all fours alone has a low pose reproduction rate: 0 out of 3 clearly reproduced all fours; sitting and kneeling poses were dominant
2. cleavage is effective for inducing cleavage: Adding it alone showed cleavage in 3 out of 3 images. However, the pose itself doesn’t change
3. from above, looking up at viewer was the most stable composition: Overhead angle structurally makes the chest visible. Cleavage was clear in 3 out of 3 images
4. hanging breasts has high nudity induction risk: 2 out of 3 images went topless. Should be avoided when aiming for costumed cleavage
5. crawling is a different pose from all fours: Body is lower and more horizontal, in a crawling posture. Unsuitable for frontal cleavage depiction
6. Costume specification (white tank top, low-cut top) enables stable cleavage control: Having the costume specifically defined prevents nudity while expressing cleavage
7. Excessive prompt combination is risky: Packing in tokens as in Condition H tends to cause element conflicts, leading to artifacts and nudity
