Here's another good T-35 page...

It has a painting of a T-35 in winter camo. Basically whitewash over the green.
I've never seen a picture of a T-35 with German markings. Some T-35s were captured, but my guess is the Germans couldn't keep one fixed long enough to put it into service. Parts would have been a bit difficult to obtain.
Apparently there is only one surviving T-35. It's in the Kubinka museum. Here are some pics of it on TanxHeaven...

There are a few good books out on the T-34. One is the "Land Battleship" Maxim Kolomiets and Jim Kinnear Published by Barbarossa Books. Here's a review...

The last one is nice in that it is downloadable and is only $2. It contains lots of photos (interiors too!) and covers the multitude of T-35 variations.
Trivia quiz...how many people does it take to run a T-35? Give up? Here's the answer...
