The design is fine, but the color is a concern. You have too much orange. I'd suggest one of two things: one, changing the orange 2x3 plates on both sides of the canopy and all of those orange 2540s (those plates with the little bar on the side) to white. You can then add touches of orange accordingly. The second option is to put white tiles on top of those studs. It would turn the overbearing orange panels into color accents, and add to the armored look of the tank. Other than that, it's a fine design! 4/5.
