If you are really into soviet heavy tanks this would be a good start

The one who deserves most is the IS-7, it was the most powerful practical heavy tank ever built. It came very close to limited serial production (a batch of 50 or so was planned IIRC) but it was cancelled due to a political snafu (although the weight, considered excessive, was a factor). If you are interested I might manage to find some stats and detailed drawings.
Personally I would like some sort of winter camo for the
T-90.
