Looks great!
a torn/faded poster on the wall, and maybe something bright...empty drinks can...ammo box etc on the ground, just to break it up a bit?
I
Digging through the stash I happened across a box of 1:48 stowage (tamiya jerry can set, to be exact). I think one or two in a nice bright rusty colour should set it off nicely. I've got to pull out the laptop in a min so will have a root through my folder of old posters as well.
Very nice work! How big of an area do you plan on covering?
Really hoping to see more of your work
Planning roughly 3' square. I've already got a lot of the storage tanks and pipelines etc done, I just need more in the way of linear cover.
(slight) further progress :

Added a coat of ready mixed filler out of a tube and dabbed at it to add a little surface texture. Hopefully this will also hide the joins. I appear to have misplaced the pieces to cover the tops of the columns, annoyingly.
Also threw a base coat on this:



Wasteland settler's cabin. One of Sarissa's French & Indian wars lot, iirc, with corrugated plastic for the roofing and a scotia grendal container at the side to modernise it a bit. No interior other than what's on the kit - there's not a lot of room inside!
Next up is to get a primer coat on the workshop and see what it needs in terms of detail painting. Aiming to get a couple of the intact industrial units from sarissa tomorrow at Barrage - and possibly a couple of retail units.
Ciao for now!
