The hand that had the thumbs-up, is too deformed. The wrist sticks out from the wrist collar.
The ear is hanging low.
The size of the sleeve on his right hadn is smaller than the one on his left. A huge lump of material on his left and very skinny and tight-looking sleeve on his right.
Also the wrist, from the right hand and trace it down to his wrist. The wrist curves outwards, but the wristsleeve curves inwards, and it doesn't look right.
He looks fat, no offense. The huge glob-like material makes him look fat.
I don't think that a spike of hair sticks out under the headband.
The neck collar, where it looks all woolly, it is supposed to be sticking up, not flattened. The orange part between the collar and above the blue part, is a bit pushed off to the side to look connected to the rest of the clothes.
I respect that you tried hard on it, even though you didn't like it. Good job though.
P.S: Is this suppose to be a chibi form? Because his headband is too large.
