If I don't post this stuff now, I never will. They've been sitting on my computer for a while.
These were all in the CGMA Fall 2012 student gallery for Fundamentals of Design. The cow head brain thing was also mine. I thought it was funny that Derek posted my notes to him about corrections in the gallery. That guy taught me a lot. Highly recommended class, but be warned that you need to know a thing or two about drawing and painting, or else you'll be like me and have to learn photoshop on the fly.
