Hi,
It seems your StuG has grown a turret. :-) :-) . Only kidding, but you strated this with a StuG if I'm right. Still the Pzr III looks good from here. As for the figures, the two running ones look nice, I don't think they are to close to the tank, I would just try to place them a little further apart and not in a straight line. If you would place the front figure a little to the left ( between the shel hole and the corpses feet), and facing to what is now his left, then it looks like he has just run past the body, and has turn left to go round the crater. The second figure I would either place a little back, or leave where it is.
Now then, the Radio Operator. I may be wrong, (and I frequently am

), but that doesn't look like a very portable radio to me. A radio like that would be set up in a fixed position, and would need batteries (or a generator) to work and is usually attached to a large fixed aerial, so the operator laying next to the tank is not a feasible storyline. I could work if you would run the battery and aerial leads from the radio to the edge of the dio, over the fence, to make it look as if he dragged it there for cover, from a exposed radio/command post.
The dead guy would nee to go back, as in that position he would have taken the full blast of said shell explosion. I very much doubt that he would be laying
there like that, less so with all limbs intakt. In short, he would have been blown apart. Try him next to the left rear of the tank, which would have been a more likely place for a smoke aswel.
Looking good sofar, keep going
