Well done! I am normally not a fan of mini scale but you managed to create a detailed work within the size. I especially appreciate the use of the Bionicle pieces for the tread covers. Those types of pieces used with regular bricks (at the expense of much time and effort) look great!
nice model. due to the scale of the tank and its accompanying background, i think you'd be excellent at detailing the exterior of a Borg Cube! at the right scale (to the Enterprise D, duh) a Cube would require a certain degree of "depth-to-foreground vehicle" scale in order to feel right/look nice. coooool!
I love the vehicle, with it's beautiful use of Hero Factory Armor, but that background is really just amazing (something similar happened with your blue vehicle as well). The background almost, should I say, upstages the tank. But great job here, I love it!
Amazing tank. It really reminds me of Transformers for some reason, perhaps its the sleekness. The background also adds to MOC as a whole. The greebles are too chaotic for my tastes, but that's just the style of them. Great job man!
