Everything is nicely done, (especially the mud) but as muddy as that base is, as seen by the tracks left by the motorcycle, I think we would expect to see a lot more mud on the soldiers' boots and the walkways on the vehicles. As a biker, I can say that the bike and rider would certainly be covered in mud.
On a technical note, it appears that one soldier is elevating the tube while the ramming operation is still going on. I'm not quite sure it worked that way. Even if Trumpeter made all of those figures in one set, they might not always be used together.

Antel, Your dio looks super, I leave the man there, he lowering the gun to be reloading. Good luck on your next project. Rick

Rick,
The gun is reloading, that's the potential problem here. The breech is open, and the rammer has the round almost fully seated. In looking at the design, this is not like,say an M109 series gun where the rammer is attached to the breech end of the gun and you can ram the projo at different angles. Here the rammer is not integral to the gun, so I'm fairly certain the round has to be rammed with the tube fully depressed.

Antal, as for the circled guy, he wasn't the one I was talking about, but it does appear that the crank he is turning is connected via a gearbox to the main elevation wheel. (A fine adjustment perhaps, where the larger wheel is for gross adjustments?) In my opinion neither crewman would be elevating the tube until the rammer is withdrawn.

Funny, spellcheck does not like the word "rammer."

Fantasztikus munka, gratulálok!
