Pretty productive day, and more successes than before, although there's still some godawful crap in there. That said, I think I'm starting to understand the difference between the ones that work and the ones that don't. The working ones are the simplest, where I did the least trying. It should be no surprise to anyone that knows me that I think and analyze myself too much, and this really underlines the value of letting that go and letting instinct do the work.
If I can really get a handle on that, the entire summer's worth of drawing will have paid off.
