Jeez...well if I ever get to the point where my skills are solid enough to attempt something like this, I'll PM you to see how you got that water problem.
scratchmod, I spent a year in the Sandbox, and as far as I can tell, if you took this build and shot pics of it with the right backdrop, it could pass for an actual battlefield wreck. The rust and metal wear are that spot-on. Your mods to the fenders, especially the on-fender fittings, are the difference between a well-rusted plastic model and a stunning replication of the real thing.
The coolest wrecks were the ones that had been blown in place before we got there, or else had simply run out of fuel or something, and had been left to rot in the Iraqi sun. On my base, there was actually a plane that had been destroyed during the Gulf War in '91, and they'd never bothered to remove it. By the time I saw it in 2004, it looked pretty cool. There was a T-55 hull, no turret, that looked just like yours here, but it had been used as a dumpster. Couldn't empty it, so they'd just left it. It had roadwheels but the rubber had been burned off, and the tracks were gone. I don't think I got any pics.
