Nice! The lighting from the torches is especially neat.
Might consider having the flames a tad higher?
Are the blocks on the walls modeled or is that a bump map? They appear to be bump mapped: when you get close to the camera the profile seems to go flat. Consider modeling some of that detail for a more realistic image, unless this is going to be animated or a game.
Sorry about the links. My normal server wasn’t working this morning so I uploaded it to another one. The blocks are actually modeled, and then they’ve got a texture mapped onto them. The file’s already at 24megs and my computer can’t really handle anything bigger, so I can’t add anymore mesh detail tot he stones. I’ll work on the texture some.
Very nice pic, and the darkness looks good. Only thing i could suggest is perhaps a halo attribute on some of the lights, to give it a little thicker atmosphere, and maybe something to emit the fire, like a little oil holder with a wick or a mini-torch. Also, the particles could be worked on a bit, the flow of the fire looks weird and the colours need to be tweeked too.
Awesome work tho, keep it up!!!
