This map is pretty spectacular. You should add width=800 or something to the img tags though.
The only gripes there really can be is that the water is too clear; you can't tell you're even in it, and the textures of the ground underwater should be changed to sand/rock textures. Other than that, first map I've actually downloaded in a long time.
Edit: Also the fact that it references textures from map_mounts. Dunno how we're supposed to have those. I think you did forget up the packaging.
