I feel that this is one of my stronger styles of painting, as anything "marsh"-related is pretty much required to be dirty/slimy/grungy (not to mention anything "troll"-related). I wanted to keep the colors on the back to those of an alligator, in keeping with the sculpted details. I decided to have the stegosaurus plates (I'm not sure if there's an actual term for these things) transition to a brown, both to make them stand out more and to represent them being a harder (calcified?) substance.
From there, I lightened the skin a bit to give more variety, and experimented with a bit of wet blending on the belly. It was a large surface with minimal detail, so I figured it was a great time to get a bit of practice in. I used a darker color than normal (khaki vs. bone white) for the spikes of the club and the claws, as I didn't want them to be too bright compared to the tones of the rest of the figure. I used a variety of browns for the hides, furs, and various wraps on the body.
I'm very pleased with how the figure turned out, especially of the wet-blending on the belly (which is a little hard to see above due to a few subsequent brown washes and the lighting). The only thing missing is a base, though I believe one of the large bases (or even one of the medium ones) from Bones II will work once they arrive.
Next week's Monday Miniature is 77153: Snakeman Warrior. I've already painted this figure (a couple months ago), so in addition I'll try to cover whatever I work on next week.
