Just some random stuff I've been doodling in class on the Mac computers. I still would prefer to use my own computer for art, but these are quite nice for blending when your tablet isn't being a stupid mofo.
Ah, yeah. GIMP is pretty fun to use, and most of it is easy. I have issues with scaling too, but once you got past that, it is pretty simple. If you can get your hands on some Adobe products, your life will be so easy. Especially on a mac, Illustrator and Photoshop are absolutely seamless.
