How This Prompt Works

Copy this Nano Banana Pro reference-guided prompt to create sketch visuals with photorealistic detail and neon color contrast. Best in 3:4 framing. Built...

Use a clean reference image with obvious subject edges and readable facial or product details before you start changing the styling. Keep the generator on 3:4 for the closest match. The mood is anchored by { "image_generation_task": { "task_type": "img2img", "input_source": "uploaded_user_image", "constraint":...

What to Change First

  • Change the subject block first: { "image_generation_task": { "task_type": "img2img", "input_source": "uploaded_user_image", "constraint":...
  • Adjust the mood through light and backdrop cues: " ] } }, "style_variations": [ { "id": "variant_01_pop_bold", "color_palette": [ "bold cyan", "magenta" ],...
  • Keep the finish constraints aligned while you test variants: " ] } }, "style_variations": [ { "id": "variant_01_pop_bold", "color_palette": [ "bold cyan", "magenta" ],...

Before You Generate

Note 1

Start with a sharp reference image. This prompt is written to preserve source identity, silhouette, or product structure before stylization.

Note 2

Use 3:4 on the first run, then test alternate crops after the base composition is working.

Note 3

This prompt suppresses text or logos. Remove that constraint before asking for branded packaging, typography, or visible watermarks.

Best For

  • Controlled visual concepts where composition, focal point, and finish need to work on the first pass.
  • Reference-image workflows where identity, product shape, or silhouette should survive the restyle.
  • Atmospheric concept work where texture, color, and mood cues matter as much as the subject itself.

Skip This Prompt If

  • You need an open-ended exploration prompt rather than a strongly guided starting composition.
  • You need to begin with a radically different crop than 3:4 instead of honoring the existing composition hints.
  • Your reference image is low-resolution, badly lit, or cluttered enough to break subject preservation.

Mistakes to Avoid

  • Ignoring the recommended 3:4 crop on the first run. The prompt's composition cues were written for that frame.
  • Using a muddy reference image and expecting the prompt to repair identity, silhouette, or packaging structure on its own.
  • Asking for readable type, logos, or packaging text without first removing the no-text constraint.

3 Ways to Adapt This Prompt

Use these as safe starting edits so you keep the prompt's structure while still making it your own.

Swap the subject, keep the frame

Replace { "image_generation_task": { "task_type": "img2img", "input_source":... with your own subject while leaving the camera and composition cues intact.

Retune the mood, not the structure

Keep the subject block, then rewrite " ] } }, "style_variations": [ { "id": "variant_01_pop_bold", "color_palette": [... to move the image into a new lighting setup.

Push the restyle with a cleaner reference

Start from a sharper or more contrasty source image, then edit finish descriptors only after subject preservation is stable.
