his body needs work. arm is disproportionately long, legs look angular and off, mid section doesn't match fat on ankles and arms, and his neck gets lost.
all that to say i like the concept, just some tweaks.
I agree with that one arm, I'll try and take it back, its hard to put my head around the other ideas though, I see what you are saying but I almost like the look of everything else but I am glad you mentioned the arm.
Arm is much better. I like the curls in his hair, it would be cool if his wings looked more like that. I'd prefer if he were wearing a diaper or a little modesty banner - maybe in the wing color. Also might try defining his body with a brown outline, like the hair, to set it off from the pink shirt. I don't know what that dot on his butt is supposed to be.
I could try and fix the wings for sure, wing foliage is tough. Diapers are for punks, this Cherub ispure of heart. I tried an outline before it didnt look that great, and the dot... why thats a beauty mark.
