This is pretty sweet...I love the lighting effects and FO, nice work.
The only thing I would suggest is to add some "depth" to the paint job for realism. You could simply use a black acrylic wash and apply to all the nooks and crannys....build it up in layers. Try it on an inconspicuous area and see how you like it. I think it would bump this piece up to the next level...
Regardless, well done
