I see you kept natural materials such as grass, stone, ores, etc. in many places. I think it'd look a bit better if you make your own walls, floors, and ceilings, giving it less of a cave feel (unless it's supposed to just be a cave). Also, varying your materials a bit more would be productive. You use a lot of cobble, but if you gave those cobble walls a stone brick trim and smoothstone decals, it might look better. Switch it up and try various materials.
In terms of functionality, it's as good as anything, but this is MineCraft, and creativity is king.
Edit: This thread is just great for architecture and design:
Thanks for the suggestions. This version is a bit out of date though, and there are new features and redesigns. I'll post pictures in a bit if I can, if not tomorrow.

There are more threads like it if you look, and they can be very useful.
Edit2: Actually meant to link to this thread:
http://www.minecraftforum.net/topic/743849-benjs-ultimate-guide-to-making-things-look-good/
They're both helpful, though i think this one is better.
