My first attempt to make an isometric picture.
<if you have a look at this picture:
Maybe i am wrong, but the turret looks a bit higher and the tracks are a bit more beneath the hull. Anyway I let myself be fooled by the hexagonal turret in my first post - i forgot that T-34 1943 had such a turret, too. So all in all you are pretty close to what you planned.
I planned T-34/76 , T-34/85 has a much bigger tower. And yes, tower on T-34 on this picture is shifted to the nose, instead of middle-based tower on Panther.
Maybe, I was a little wrong with proportions? If somebody else notice it to, I'll fix it.
The turret looks like the T-34-85 variant but the rear seems wrong to me its too short. In all T-34 tanks the turret was not in the middle along. Sorry i am a bit picky according to tank models of ww2
