Hi Zak,
Weird looking machine that. I agree with Haddock, the base does not do it for me, I think the base could do to be a bit bigger across, so tanks sits centrally with groundwork all around it. At moment looks like Tank has been airdropped onto peak of mountain........?
Though, I can see what it is meant to depict, running over trench tops.
Only a constructive observation from me.
