Mark,
Great diorama as always - It’s good to see South African armor builds (these two kits don’t seem to get built very often if you can judge by what’s posted online) and that‘s a nice adaptation of those Evolution figures of the girls taking pictures in the Russia/Ukraine conflict. I probably would dusted the vehicles up a bit more myself, but it is an exhibition after all, and the light weathering you‘ve done looks really good.
I built the Rooikat a year or so ago (nice kit, like you said, goes together very well) but still need to finish painting it - your work has inspired me to get it done!
