That's really nice Maffen. I hope that Zvezda kit didn't give you too many headaches.
Looks great!
I'm thinking about making a very similar diorama myself. I have a SU-85M waiting in the wings and I am planning to make a similar scene, but with some wooden bunkers, hand-to-hand combat going on, as well as taking out the SU-85M with a Hafthohlladung contact mine in place of the Tellermine.
