Aww, now that's really adorable! X3 And from I see you have improved on your anatomy as well! If you were to change anything (probably not, but keep it in mind for the next time yeah?), be aware of how the shape of a foot will look like when you're looking directly under it. Something I always use as a tiny rule is to keep the toe aera wider and bigger than the heel area is. Especially since the front of the foot will be closer to the viewer than the heel most times. Don't have them equally big, it isn't correct anatomy wise. Try it and you'll see what I mean. Keep up the good work, this forum doesn't have enough chibi. :>
I really like the way you colour with markers, you're good at it. Better than I am anyway. Other than what cocohints already mentioned about the feet, and proper foot anatomy, I can't find anything else that really stands out. Keep up the good work, I like your style. >w< Very cute.
