Yeah, the HULL is fine but the TURRET is the problem for me. Look up some of the WWII tanks and compare them to modern tanks. Turrets in modern tanks look squashed flat in comparison but the modern tank is still bigger. So for me that kind of makes the design just a bit, impractical. If you read some of the stuff about WWII Tanks you can find out more as they kind of sussed it out mostly during this era.
