Which of these should I color and shade? (Patreon)

Heya friends, I was hoping to involve you all more in the process and kinda gauge what it is you all would like to see! I have four old sketches that I've been meaning to revisit but haven't really had the time or motivation to do so. So tell me what y'all would like to see! And feel free to leave comments if you have any suggestions for further sketches!
