Pretty impressive scene!
A few nitpicks ;)
The perspective on both sides of the street is inconsistent, specifically in height of point of view. This height is where the horizon line crosses the foreground (or any) building: above the doors on the right, barely above ground on the left. The lil guys are sized accordingly to the right side, but since they are closer to and interact more with the left, they look very small.
For composition reasons, Zilla might be taller by a head or less. I'd also tone down or remove the purplish square building part at top center.
The car looks static, could use more flame or smoke trail connecting to it.
I guess I thought the preview was cute. Changed preview. Thanks.
Stunning artwork! I agree with @felchqueen 
Unless you're Helm or DawnBringer it's pointless!
The preview text probably should be 'your submission is pointless' :) Lovely work!
I always find it a bit weird when people say that. You're welcome though. :)
