I don't facepaint so my critique will be kind of garbage, but from a normal artists standpoint I think it would be interesting if you added highlights to it so it pops more. Like made the tongue or black glistening and textured. And if you made the tongue longer, though I suppose you don't have a lot of room for that. Everything else looks good though, it's unique and fun, I would just try to add some highlights or just all around shade it a little, I don't know if you can blend some face paint together and possibly make gray to make the teeth look shaded. This is of course you want to make it look a tad more real and stand out more, I know venom is a comic villain and that doesn't need any shading or anything because he's essentially a cartoon. Sorry I couldn't be more help.
