Paint.net has it's turn

Because I seriously need to be drawing more, even if it's just grubby sketches like this one.
6am this morning and I was already up and bored out of my mind. I don't start till 9:30 so there I was staring blankly at my screen cursing the early hour and the lack of decent things to watch. So I cracked out the old Paint.net (lol but it loads a lot quicker than Painter or Photoshop) and played around with some of the weird and wonderful brush settings. Took me all of half an hour but yay! arts! XD
