In order to learn art (for The Tunnel! And for fun as well/general game dev skill-building), I started doing some pixel dailies. I'm mostly doing the Lospec ones (but trying some of the Pixel Dailies twitter account ones as well). With my schedule, I will almost certainly not be able to keep up an actual daily practice, but I only went to grappling once this week (feeling under the weather) so I had a little time.
I realize some of these -- a LOT of these -- will be fucking awful, but I appreciate how much they've gotten me to just try new things.
Also! It's helping me make progress on my main project! Last shot is a WIP of the title screen, which is just starrrrting to emerge.
