Spelljammer 3D art: Siege engines

Hey all:

I've been taking a stroll down the long and difficult road of 3D
illustration, and finally my hard work is starting to pay off. I've been
slowly building up my all-time favorite Spelljamming ship, the Elven
Man-O-War. It's still a work in progress, but I finally got the deck
armaments done and created some close-up renders.

I'm using trueSpace 6.6 from Caligari (http://www.caligari.com
<http://www.caligari.com/> ) since I cannot afford the high-end 3DS Max.
But it's just a hobby, and trueSpace does a good job.
