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!
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
