Where do I begin?
Well, new textures a must. JK textures generally suck. Once in a while you can take a few of the better ones and make them work, but general advice is to avoid them when possible. There are plenty of good texture packs and sites out there that you can use.
Architecture. Blocky, blocky as hell. That "rock" tunnel for instance. Cut it up... Cleave off a bit of the sides, and start messing with them. There's a couple of tutorials on how to do this here on Massassi.
Lighting... Please, fix the skews. Once again, there is a tutorial on how to fix these, so we shouldn't have to be seeing them anymore. In one shot, your lighting looks great, but the rest, don't seem to have lighting, or if they do, are severely lacking the style and quality of the lighting.
