It's nothing impressive but I only used a few autonomous strokes. I use Open Canvas 4.5e Plus. So there you have it, Techgamer
. Everything you see here was digitally painted, but I used only my mouse. No fancy custom-brushes, scripted filters, or any of that crap.
I'm not really happy with how the planets' shadows turned out, but really this was a speedpaint. You can see some artifacts around moon's outline, which was a result of me trying to blur the outline to give it a smoother, rounder look.
