Things I think you need to work on:
6 ) Replace the wheels with an extra pair or bigger ones, Otherwise the threads look outta place and almost about to tear off the suspension.
7 ) The front armor looks stepped, almost inviting any survivors of its discharge of firepower to climb up and raid the raider with grenades and crap. Make it sloped, also giving another chance against bigger projectiles and making it overall cooler.
8 ) Cover those threads! A well placed shot and BAM! The Behemoth turns into a crawling hunk of metal. At least the frontal ones.
9 ) Has some nice dakka, but those tiny little side guns are begging for an upgrade! Double the trouble or swap them for bigger ones.
Despise those things, the feel and badassness are there, just kick things up a notch. Oh and it was a smooth move putting the boarding ramp on the rear, unless you have some really well armored infantry units, droping regular grunts on the front would be a massacre. Oh wait... Hope I helped
