I drew this last Friday night/Saturday morning after I got home from hanging out with friends. One of my favorite digital toys to play with is this freeware called Alchemy. There's so much you can do with it despite it being such a simple tool. If you feel like doodling I recommend trying it out, there's a few really good tutorials on you tube.
