Hi Hogzed,
Welcome in! This is a great place, you'll enjoy yourself!
I once experimented by doing a diorama on 3 levels and displayed in a acrylic case. Used putty to form rolling meadows, dried moss for tree's, sprayed a mist of flat white over the landscape, to simulate a snow covered landscape about 5,000 ft below the viewers level.... where I mounted a 1/48 T-28B by the left wingtip in the front side of the display box, and a 1/72 T-28B's right wing to the back side of the box, about halfway to the base. Also along the front and back of the inside, I mounted little "L" shaped pieces of sprue, airbrushed some cotton, and made scattered clouds (also camouflaged the wings attachment points with a few passes of the airbrush on the outside.
Viewed from in front/above, and squint your eyes a little bit, and it looked like the T-28's were flying through the air. I sold it to a co-worker before it was finished, and I have never done another one.... it does make for an enjoyable project where several scales may be incorporated.
Maybe even a couple P-51's (1/48 & 1/72, or 1/32 & 1/48, strafing through a village or town or ??
Greetings once again and come around anytime!
