I risk adding unnecessary polygons :/
What's the poly budget for vehicles?
EDIT: How's this?
EDIT:
Turret is mostly finished.
Cannon and coaxial gun are finished.
Model is 5948 polies when triangulated. I assume that's getting to be a bit much :/
EDIT: Decreased wheel detail a bit, to reduce the poly count by about 1100 polies. The gap in between the two halves of each wheel will now be textured on, instead.
