Interesting but a bit one dimensional still, maybe due to the nmf reflections you're using it makes the entire fuselage very box looking, also some very odd colouring going on around the leading edge of the tail fin.
Final observation is that the shadows cast by the wing/tail would actually blend in with the bottom part of the fuselage which is already in shadow so there wouldn't be a double shadow cast. Plus what is going on with the shadow cast by the aerial, totally wrong direction compared to everything else.
