I have always thought that K&C's tank-killers are great buys. The more open tops allow for beautiful K&C figures and the big guns mean business. All the open vehicles are fun (to collect - that is - not so much if enemy airpower appears).
Also, most models when I was a kid were of tanks (usually just a Panther, Tiger and Sherman). My uncle made models of every U.S. naval plane in WW2 (including a huge Catalina and B-17) as well as dozens of other planes from WW2 (his surviving Corsair and Stuka still hold up to modern standards); he made models of many WW2 ships of all stripes and he made tanks. He also had to go to the Hospital for respiratory problems involving glue and paint but that's not the point (other than to prove how hard he worked on his models, which he shared with Dad). We showed him our collection 2 years ago (he is sick now) and he loved it. He has moved on to countless other hobbies (he's a do-er) but he still loves the models and, although a bit of a rivet-counter, he thought K&C did the best job.
Of course we don't have any Warpark...
Sorry just thinking "out loud" (or typing as I think:redface2

Anyway, to the point: your photography and diorama are perfect.
