excalibur sonic quick sketch

When I saw the ending of the game sonic and the black night a morning in IT class (messing in youtube XD) I just had to draw him in my next physics class...I know, came out pretty lame, but hey, again, for not having anything to base myself on, I think I did a pretty good job. Yeh, this a quick sketch, XD took like 15 mins or less, scince I did it on the first 15 mins before the teach got to class lol, then she took it from me. The colouring came out lame scince I rushed it, like 2 minutes when I was packing up XD

what u think?
