Sketch I did today of the Crystal Orb of the Suffering Thoog. Modified with Paint.net for color and various effects. I rarely do much art anymore but once in a while I will put something up to mix things up. I find sketching to be much more draining than writing for some reason.
Just to show the massive amount of cleaning that Paint.net can do, this is the original scan (sketch on top of a photocopied crystal ball). The entire process (blank sheet to finished pic) probably took 1 hour. Not bad for a free program.
