The rolled out track looks good, as does the suspension and ground work around it, in the last pic.
A couple of suggestions for your consideration. The decals are really silvered and detract from a really nice model- so you'll want to address those.
Perhaps propping open a hatch or two will also give the viewer the impression that the vehicle is immobile, and the crew is preparing to address the broken track, or abandon the vehicle.
The buttoned up look of the Ferd doesn't initially convey the concept to the viewer that the vehicle is damaged, (just my opinion though). You've got a good build going here.
As you progress adding some figures, either Germans inspecting/discussing how to repair the damage, or Russians inspecting an abandoned vehicle, will really tie this whole thing together.
Good luck as you move through this build.
