I like the attention to detail. I am guessing that this is supposed to be a scene during the first winter (1941/42) of the war on the Eastern Front, maybe around Moscow or Leningrad.
The German soldier has had the good fortune to receive a winter-wear greatcoat, but has not received (and so had to improvise) effective cold-weather headgear and boots. But he does not appear starved or emaciated, so the diorama does not suggest a Stalingrad story to me.
The Russian soldier is from a unit that is either a high-prestige formation (a Guards unit) or a new arrival to the front in the early war period. He is fully equipped with all of the latest and best kit. Rather than just a common greatcoat he has a sheepskin coat (which would be more rare later in the war) and an SVT-40 rifle (also more widely distributed at the start of the war). In total I would expect he is a junior officer or senior NCO, but early in the war the Red Army eschewed insignias of rank.
One particular detail I notice is that the Russian soldier has his gloved hand covering the action of his rifle. A small detail, but from my understanding an experienced winter soldier would indeed prioritize keeping the action warm rather than just holding the rifle by it's handgrip, particularly with a semi-auto SVT (vs. a Mosin bolt action).
Another detail is that the Pz. 38t appears to have had it's hull MG removed. All that is seen is the gun "tray". This too is a detail I appreciate, as a tank crew leaving a disabled tank will be inclined to take their MGs with them, and a victorious force scouring a battlefield will probably pick up the available MGs first.
Oh yeah, and I like the snow effects too.
