I really love this. I made a version of that tank myself about 7 years ago, inspired by the idea of a battle tank with legs. It sucks compared to what I can make now, but I always thought that scene was one of the greatest in the whole film. Didn't know how to poly-edit when I made this as I was a noob at the time. [link] I've been wanting to make an updated version for years.
Again, this is a great piece and i'm impressed with what you can do with Sketchup.
wow what program do u use? your excavator is cool too... your work looks pretty realistic.. sketchup is kind of ... well sketchy looking .. i know how to use 3dMax but i'm to lazy to use it this days so i use sketchup witch is much faster but less realistic looking T_T
