sorry to say, but i can c right away that he didint trace it
the drawing looks neat, but the head is deformed, and doesnt looks like goku @ all, and sorry, but i dont like the hand either, the finger next the thumb of the (for us) left hand is to pointy and the other handlooks strange...
it looks like goku is wearing a skirt, i cant c the lines where the other legg begin, :S.
the hair looks nice, but also has some failures, i c a way to thin hairlock.
overall still looks nice, although all the minors, but if i really have to c goku in this, then i really dislike the picture
