Don't give up on the Art Critique forum. It's underused but is exactly what you're looking for. Of course technical comments are OK there. We should use that forum a lot more. If you post there I'll respond. If I don't respond, PM me to remind me that I said I would!

I actually like where you're going with this image. Of course the lights wouldn't look quite like that in a real dungeon, but I've been real dungeons (lots of times) and the reality isn't as interesting as your take on it here! I like the vibrancy of your lighting.

The skeleton looks odd to me, and is too distracting. It looks as if it's about to grab the girl, while she appears disinterested in it. An anomoly. The girl's pose, the direction of her gaze and the candles/lamps all drag the eye to the right of the picture ... but then there's the skeleton doing its thing on the left. That's the compositional feature I'd want to resolve.
