I actually painted a miniature...
Seriously, this is the part of the hobby that I really stink at. It's not so much that I'm no good at painting (I'm not great), but I really just don't enjoy it. I enjoy having painted figures but the process of getting them there isn't as entertaining as it is for some.
Anyhow, the figure I chose to paint is one that I sculpted myself, back about the time I first started sculpting for real. I was on a zombie kick at the time and wanted to have a big ol' Mega Zed to slap on my table. The resulting figure wasn't really suitable for molding and casting, but it was still cool. I based it up and it sat on my shelf.
The figure is a nasty one with horribly mutated muscle and bone structure, a talon hand and a giant piercing spike. His face is deformed, exposing crooked teeth and eyes of differing sizes - one bulged out, the other in a deep socket. Oddly enough this mutant freak seems to have found the same amazing line of pants as the Incredible Hulk and as such, I have painted them an appropriate purplish hue. He works wonderfully as a Mega Mutant as much as a Mega Zed and can be seen below menacing a group of post-apocalyptic wastelanders (converted from French Indian Wars figs).
