Beautiful. The AAT has always been one of my favorite vehicles in Star Wars for it's unique and unorthodox design. I was a little disappointed with the 8018 version, this beefs it up nicely with a colour scheme that works better anyways. I'm still not a fan of the main cannon, but I'm not sure what could be done to improve it.
BTW, what set did those dark tan rounded corner slopes come in? I only recall seeing them in black, dark gray, light gray, and navy.
