Here are some closeups of that Chainmail-line Ogre Mercenary I used as a cave giant in my game on Sunday. I can finally show them off because the players have seen this guy in person.
The chainmail line is very 2D. Even this guy is very flat front-to-back. The upside is that I could make him fit easily on a battlemap without a giant base.
You can probably see pretty easily that I didn't do all that much blending on this guy. Colors tend to start and stop abruptly. Honestly, I just got tired of painting him at some point, did some touch work to make him look good enough, and stopped. Still, he's a pretty good paint job and I expect if I need more giants in the future I'll bust him out again.
