hello, my first post here, what an amazing place. I could spend hours just looking at pictures and reading stuff (...wait I just did that...)
now my "problem"...
I scratchbuilt a miniature after this concept art:
I used the left one's pose and made him a bit more bulky and additionally gave him the right one's "spikes" on his back. you can also ignore the two tentacles coming out of his chest, replaced those with a pair of claws.
anyway...how would you paint those? I want to give him an organic, alien look, with some striking contrasts (I thought about painting the spikes black, and red towards the ends, but I am pretty open minded there...)
