This is my first time doing a critique, hope it's ok x
First of all this so sooo cute! The colouring is exceptional and it looks really nice to the eye because of the fairly simple colour palatte. I just have two comments: with the placement of the hair and that face shape, at first gance the cheeks looks a little strange, the left one appearing to be separate from the rest of the face at first and the right one extending a little too far so that it shows the ear (which on this angle would probably be partically covered by hair); and the right arm needs to be on a little more of an angle or it looks a little like it's being twisted backwards. If you look at the shoulder carefully it bends in a slightly strange way. The colour is amazing, I love your style for the eyes and the detail on the hair is breathtaking. Keep up the great work!
I hope this was helpful! ^^
