I used a hybrid workflow with the images: the initial figure done by hand, then AI to get a reference for some nice details like trees and fingers (I suck at those), then manual lineart, interior sketches, and texturing. So it was used in the process, but you don't see any of the generated output. Itch policy, IIUC, is to flag such things as using AI anyways.
The walk phases are totally hand drawn, though. I failed miserably when trying to get what I want out of AI there :D
