also the christie suspension used by the BT (and later the T-34) was very unreliable and bulky. Also the Soviets already had a project for an uparmored Bt, know as the BT-SV and BT-SV-2.
You removed deco layer and added low quality changes. I say this creation has been ruined.
If this were to be the reality, the Germans might have had a bit of a easier time during the 1942s and 43s, due to the T34 really being THE workhorse of Soviet armor, but if this were to be a mid to late 1930s project, the ammo would be lying all around where the crew has space to put it, not in a special compartment, there also would probably be atleast some sort of a proper cupola, and likely it would have a more proper gun.
