I love the serious thought in each design! The first one looks like it would function really well as a stand alone tank, but like a very large mecha could pick it up by the band across the top and use it like a machine gun.

The landship style tank has such fantastic detail, i love the little sticking out/swing round seat! I can just picture the top of that turret showing over a hill or peeking over the tops of trees, the reveal as the camera panned round to reveal it as a huge tank. It looks perfect for getting in position, having the radar sensors and guns the only thing exposed, and earth shattering decimation it could cause.

even a pesky crowd of rioters at camp crying out for more rations.

damn, brutal times! The world you have behind these designs really make them.

That last one looks like a real all terrain bad boy, it very much looks like an urban tank, prime for rolling over crushed cars, broken bits of building, and the twisted remains of enemy machines. I am just so impressed by how the story you have comes out so well in the design.
