i found this a couple of months back this may answer the wireframe question unless there is a better way that i am not familiar with. http://blog.environmentartist.com/?p=724
looks good! Can you post any wireframe / texture? really like the texturing. For ur final presentation of this piece I'd probbaly improve on the lighting.
Lookin' pretty nifty. If you're looking for topology critique, it'd be good to see the wireframe in quads, and a bit more contrasty. As it stands, its hard to see.
