I really like the tile effect you have going on. Reactive armor FTW! Also, interesting how the bit that I guess is the exhaust looks like its glowing blue. Nuclear tank? Anyhow, love the attention to detail. Like the fume extractor in the cannon!
This was cool to look at. The "ablative" armor is nice gives it that reptile look. The heat commng out of the rear vent is a nice touch (needs more sand kicked up I.M.O.) Of coure the desert color scheeme is really a great touch as well. Your use of long range and medeum range weapons make for an effective weapons platform.
