Recipe
The examples above were generated with Nano Banana Pro and Seedream 4.5. The recipes below are written for GPT Image and Midjourney, so treat the settings as a starting point rather than the exact run.
A description in plain sentences. This is the version to start with, and it works on any current image model. Settings below are the ones we used on GPT Image; treat them as a starting point.
The recipe is the style, not the picture. Put your own subject in and the highlighted part of the prompt changes.
A technical anime style line study of a pilot in a hard shell helmet and suit, drawn entirely in fine ink line with dense panel detail, seams, vents and fasteners. No shading beyond a few solid black areas, the figure floating on white with thin schematic callout lines running off to small blocks of technical text in the margin. Half character drawing, half specification sheet.

Tips
- 1No shading beyond a few solid blacks. Line density does the rest.
- 2Callout lines and margin text are what make it a study rather than a portrait.
- 3Float it on white. A background turns it into a scene.
