This really is a realistic piece. I would suggest a diaroma steup and then some more shots as it would really showcase the realism and make this piece into a scene worthy of high rez wallpaper.
Very impressive. Without a doubt the most realistic Imperial Fist tank I've ever seen.
The only thing I think needs to be improved is the exhausts, you should drill them.
I also took a look at your site. Some very nice stuff there. Starkt jobbat! :)
