Random Sketches

Here are just a few rough sketches I did in the past few days during breaktime and/or during class in school.. I have no time to color them yet..>.>

Please go easy on me. I am still learning how to draw guys!
Btw, the troll on the lower right is a product of a sudden burst of anger..lol

All are done without reference.
