Back to business to my problems of my art. I have sketched another artwork and need CnC on it. Here:

See, you do the shading perfectly, but the facial expressions and head are the only problems that you seem to have. You don't need color with these either. Well done I must say. 8/10

 

Ah. Well yea that's my problem. XD I studied too much on shadows and body shapes. It's just the head I don't like drawing. Although my head in the Xmas pic is how I really look like... I think . XD

Thanks. ^^
