After a few experiments I found this to produce the most consistent results for me
> make this a how to draw example, with 4 progressive changes showing the development of the minimal sketch (no text)
Each change should be in single file/row starting from left to right
It should be pencil sketches on white background only, no colour
nice - I tried it with aging a pic and it was very prone to mode collapse (just generates the same image). Generating multiple sub-images in one seems to be more robust but still can be hit or miss.
4 progressive changes showing development is how you teach ai to think in layers. most people dump everything in one prompt. breaking it into stages gives you control over the creative process. smart approach.
