You can see though the hair on that one guy, 
(villian I gess?)and can see part of Vegeta's arm 
though the hair. And I thought that sketches had 
shadeing. And back to the villain I see alittle 
bit of his other eye on the pencil board...and 
not on the sketch. Also Iv'e NEVER seen a pencil 
sketch on graph paper. I'm not exactly an expert 
here and I'm not trying to say that marc is lying 
but I seems to be a nice, VERY nice fan 
art...just a personal observation. ~_~; .......
