I like it. Looks kinda friendly in a squirmy way
Nice floor texture.
Can’t tell if those holes above the mouth are eyes or nostrils… Maybe he doesn’t need eyes?
If they’re nostrils, a bit more definition might reinforce this, if eye sockets then eyeballs with a bit of texture and specularity would define them. Perhaps snake-like eyes with an oval slit eyris? …or slight bulges with the nostrils in the middle. Maybe even glowing eyes with a small halo lamp inside them (not messed with lights like this before so unsure how this would work out)
A tongue lolling from the side of the mouth would make him look a bit confused and frightened, or sticking out a bit might make him look even more surprised
I like this concept and am looking forward to seeing where you go with it
