Well, I like it
Cool lighting / reflections. The scene maybe still looks a little too "polished", e.g. textures / texture mapping are too uniform and clean, but that's normal in that state of development. Plus (as I'm a shader effect guy), there is a huge untouched potential of shader techniques and effects that could be applied in order to make the entire scene look more realistic, such as advanced normal mapping, parallax mapping, light effects (shafts/rays, lens flares etc.), SSAO / HBAO, dynamic depth of field and the like, but I guess that's not yet on your current todo list since you're saying you need to do things like collision detection first.
So keep up the good work !
