A Few Study Sketches

For the sake of submitting something, I show you my sketches from assignments in college. Yeah I know they are not great, however as I slowly get rid of distractions and what not, I will be drawing and doing alot more artwork in my free time. I am slowly learning more on character design, so next week I will be submitting a few more sketches and maybe a abstract piece....if I can figure out what to do with the render x.x;;. Anyways, you all. Peace.

P.S. Any tips on drawing are always appreciated. n.n
