I bought myself a Badger 105 airbrush and took a class offered by CK Studios. Best decision I've made in a while. I'm not going to go into detail on what I learned, but I will say that if you're interested, look up CK Studios and give them a chance.
Transitions, transitions, transitions!!!
This last shot is what roughly 20 years of progress looks like. I haven't been painting the whole time, or I'd probably be a lot better by now, but 20 years ago my best move was pretty much to stay in the lines. Huzzah!
