It was nice outside, so I sat in my backyard and sketched some oompa loompas. None of the sketches really grab me, but I'll use then as reference when i sculpt it in zbrush and pick out parts I like from the different sketches. I didn't really want to base them much off the movies, the book mentioned they wore deer skin clothes and had crazy hair.
I also sketched out the rotten vermicious knid. he's got a tail with a hand at the end to grab oompa loompas by the head and then toss them in his mouth.
