Looks cool, but it's so flat/dull/ colorless. The engine could be given some more detail. Actually the thing that get's me is that you used a 1024x1024 texture for something that could easily be 128x128. It's a waste of resources if you consider that. The unwrapping also leaves me wanting. Such a small object is pretty easy to unwrap manually. However, your model itself was made very cleanly, no funky edges and whatnot so cudo's on that. Give it a revision, I'm sure you can make it into something amazing.

It looks so cool mate. Good job!
