the models and textures are nice - they seem to express the theme nicely - nice work...

i'd work on the composition tho - it's a little unfocussed... each element takes equal precedence - i'd choose an angle that places one of the objects in the foreground and maybe try to work with depth of field to create more of a feeling for the depth - don't be afraid to place an object partially outside of the field of vision - it can make for a more interesting scene. Also you could light things a little less evenly so the shadows were darker - try two different colored lights and an ambient light. Try working with decay rate to get more variation in the shadows.
