Hey, have I actually posted in here yet? Weird.
Anyways, I think everything looks pretty good so far. And kinda weird but I think I like that purple hornet over there with the blank eyes more than the normal one, but they give off different feels, so... well, it still looks fine to me.
Also, just a small thing, but the spikes look a bit out of place to me. Maybe they could be the same color as the wall or thin and modeled like stalactites that inexplicably poke out of the walls, but that might be too much trouble.
