Here's one I painted for a friend, flail snails are one of their favorite DnD monsters. Lot of firsts on this one: Using UHU glue for slime effects, smooth color transition (red/yellow eye stalks), played with some red/blue duo pigment for the shell, and I'd never made a desert base before. I'm pretty happy with the results!
The detail on that is wonderful. Just noticed the green trails of slime sticking to the snail...
That's UHU glue mixed with some green paint! It was the first time I've tried doing something like that with it I had a lot of fun making those effects
