OK, so we have what appears to be a Jagdpanzer IV-style tank destroyer chassis with two main guns, plus a small nozzle that is probably a flamethrower; a relatively short bow gun that's pretty clearly cannon caliber; a smattering of weapon ports to fire out of; and a large cannon with an odd mounting system coming off the right side. Then, mounted on top of *that*, we have a fairly normal turret--main gun, coaxial machine gun, roof-mounted gun for close-in enemies too fast for turret traverse, side-mounted missiles--and on top of the turret, an elevated platform that appears to be dedicated to anti-aircraft fire.
I'll be honest; I actually know a bit (for an amateur, anyway) about the design of tanks, and I don't get some of your choices. The guns in particular--why two different kinds on the front, and why add another one to be badly aimed by a bow gunner? And do you really need two machine guns on the roof, which everyone is going to be shooting at even more than they normally would because of the radar dish? Still, I get what you're going for. Tanks with too many guns are cool.
