Base Prompt
Cherry blossoms and the subject’s relationship observed at close range.
A00: control
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: Bust shot with a park cherry blossom path in the background. Several cherry trees visible in the background, but flowers are positioned away from the subject. A few petals scattered on the ground visible. White blouse worn. Framing is bust to waist up.
A01: sakura face
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: s1 has a composition close to control with cherry blossoms densely visible in the background. s2 has 3 subjects and cherry blossoms placed in the foreground around the faces. s3 has 2 subjects. The side effect of ignoring the “1girl” specification occurred in 2/3 images. Cherry blossom density is higher than control.
A02: sakura bust
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: With sakura added, cherry blossom density in the background is clearly higher than control. Cherry blossoms spread across the upper frame, filling the area behind the subject with white to pale pink flowers. Framing is stable at bust shot. Subject is stably 1 person. The contrast between blue sky and cherry blossoms is stronger compared to control.
A03: petals face
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: Framing shifts to a face close-up, with the petals specification producing multiple small petals falling around the face. Petals scattered on cheeks, hair, and shoulders, with 1-2 clusters of cherry blossoms placed as foreground branches. Background is white and blurry, clearly a different screen composition from control. The petal scattering expression is stable across all 3 images.
A04: branch frame
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: The branch frame specification places cherry blossom branches in the foreground, with flowers surrounding the subject’s face in the composition. In s1 and s2, branches flanking the subject from left and right are visible. Individual flower petal shapes are clearly visible, and the amount of foreground cherry blossoms is clearly different from control. Framing is face to bust shot. Subject stably 1 person.
A05: pink bokeh
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: The pink bokeh specification covers the background in pale pink to white blur. s1 has a cherry blossom tunnel-like background with pink bokeh spread across the entire frame. s2 had the side effect of 2-person composition. Individual cherry blossom forms are blurred and unclear, but the overall pink tone is stronger than other conditions. Framing is bust shot.
A06: hanami bust
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: In s1 and s2, the subject is wearing a floral kimono, with the “white blouse” specification ignored. Hairstyle also changed to an updo, pulled toward a traditional hanami image. A pose reaching for cherry blossom branches appeared in 2/3 images. Cherry blossom density is higher than control. The side effect of hanami triggering kimono conversion is prominent.
A07: petal hair
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: Framing shifts to a face close-up, with multiple white to pink petals scattered around the hair and shoulders. One cluster of cherry blossom branches visible in the foreground. Background is white and blurry. Compared to petals face, petal positions are more toward the hair, but the overall impression difference is small.
Summary
| Condition | Blossom density | Petal scatter | Foreground branches | Side effects |
|---|---|---|---|---|
| control | Low | None | None | None |
| sakura face | High | None | None | Multiple subjects (2/3) |
| sakura bust | High | None | None | None |
| petals face | Medium | Yes (around face) | Small amount | None |
| branch frame | High | None | Many | None |
| pink bokeh | Medium | None | None | Multiple subjects (1/3) |
| hanami bust | High | None | None | Kimono conversion (2/3) |
| petal hair | Medium | Yes (around hair) | Small amount | None |
For close-range cherry blossom expression, different uses are effective depending on the goal. Use petals face or petal hair for falling petals expression, branch frame for branch-framing, and pink bokeh for an overall pink background. Note that hanami triggers kimono conversion and competes with clothing specifications.
