I find I'm never as creative as I am when I should be doing homework. Last night I really, really needed to be working on a paper. I decided to draw instead. It's still a good use of my time, I could have been watching TV, after all. Oh wait, I watched all of Being Human series 3 too (my god Aiden Turner is beautiful). hmmm, getting distracted again.... Point is, I did a few little studies of the type I should really make a point of doing more often in order to keep my skills sharp.
Looking at all three I can tell my interest was not holding until the end, though. The first started out as a careful, academic study, the second one is much closer to my typical scribbly style, and the third is barely started, though I like outline look as well. I may try a few studies in which I concentrate on a few simple lines, because it's so hard to do right.
