I do like the fire on the torchlights. One thing you might consider (yup I'm agreeing with everyone else lol) is to make the radials much, much brighter, then fiddling with the falloff. That way, you still have the feel of a dark image, but you can make out more details. The spider model looks great. You know what would be cool? If you could figure out a way to have compound eyes on it. I think it might look a little more monstrous and a little less "cute" (it's hardly cute as it is lol). One more thing. How about an adventurer poking his head out through the door? He could be carrying a torch, which would also help to brighten the scene. Also you could put a skeleton arm in another shackle on the wall, with the rest of it lying nearby on the ground, as if it either gnawed off its own arm and died from the shock, or decayed and rotted and still fell. Just some ideas for you. =)
