After watching Tsubasa Chronicle: Tokyo Revelations, I felt in the mood to draw Syaoran. http://nodokafreak.deviantart.com/art/Syaoran-Sketch-99145411 CnC?
The head is too wide. From the right jaw to the ear it is too stretched out and awkward looking. I also think the eyes are too big for the head. In general it'd be pretty much fixed if you simply made the head less flat and shrank the eyes down a mite bit.
Already commented on it. The yes could tune up a bit and then the head is wide just like Trogdor said and the neck could be a bit thicker.
