I say that it looks nice, and the animations are fine, but as Fuzzyman said this looks like it would be more for dwarves, but i guess that you can use it anyway once u would actually import it .
Hmm... I don´t really like it - if it´s a naga-weapon. To me it looks more like it´s built by dwarfs Naga living in the ocean wouldn´t built something with wheels. Some kind of giant creature would be better I think But all in all it´s a good model
just tested it in-game. very nice. has anims, a particle emitter, but the skin is a bit lacking. if it was a bit less monotone and more high-rez and there wasnt a couple errors in the UV mapping, i would give it a DC.
