I'm not really gonna say anything about technique and whatnot but I realize you don't do a lot of work with more than 1 figure in the picture and this is rather different. The physical contact between them makes the impact and how the hair wraps around both of them is a beautiful concept to me.
I don't know if I'm just digging too much into it, but the contrast between the two of them, one colorful the other in a grayer palette, it really leaves a lot to the audience to ponder. Anyways, can't wait to see this finished!
