I drew good 'ole Man Thing months ago when it was the weekly topic on ComicTwart. All of the sketches there kick ass all over mine, with Tom Folwer's being my personal favorite.

And here's the digital underpainting. Frankly, with only a little bit more work, I think this could be my favorite image of the three.
