A while ago I decided to get back into the habit of doing daily studies. They're super fun to do and really help get the creative juices flowing in the morning. Each of these took about 30 to 60 minutes, the goal is to keep it simple and practice fundamentals. (Not that it matters, but they're all done on one layer and without zooming in. I don't know, but keeping it straight-forward and oldschool like that feels really revitalizing. Try it, preach it.)
