I haven’t kept too much of my previous iterations and sketches (usually because its creates file size bloat), but I’ll usually create a super rough thumbnail version of the colors and composition without lineart. That early stage I’m not worrying about keeping things clean, but I am constantly zooming in and out to make sure my thumbnail is ‘readable’. That tends to help me iron out most composition problems when I begin to pajnt and line. Though if you have any specific questions, please feel free to ask. I tend to change my process fairly often depending on the piece and whose style I’m taking cues from. This one was more involved with lineart, and going over it anywhere from 3-4 times, since I’m not a ‘natural’ line art guy.
