Looks good.
Particularly like the way the various "lines" cross over the diorama.
The spade on the gun needs to be sandbagged, though.
I have a number of memories for that fine old kit, and going back to its release (dang, I'm old). Only real knock on the kit was the lack of a guy on a field phone (all of the guns in a section were meant to be connected by wired field phones to the section commander. And that worthy connected to the platoon/battery commander.
The bleow is informational, not criteque.
Becasue of the fickle nature of cameras, monitors, and the like, it's very hard to be hard on color selections. But, by all accounts the 'Rats were "brown as a nut" to a man; which can be a hard fleshtone to render.
The accounts differ, too, on how much was unhitched when a gun was placed. Several accounts state that the limber was left hitched up, especially when using the ready service ammo aboard. All the better to "shoot and scoot." Otherwise a lorry brought the anno up to the gun--a hundred rounds for an artillery barage is a sizable weight.
