That is outstanding!
Looks very much like its been baked in the sun and playing in the sand. Very Nice.
The tankies are also very well done. As for a dio? Put it on a simple base. A dusty track with a couple of dessert plants. That would look nice and not distract from that excellent build!
I imagine that is a big lump and a worthy diorama would be huge enough to give it housing problems.... However, a knocked out, burnt out enemy tank and a couple of figures, examining the damage..... that could look nice as well.
If you have a house and bank account big enough, a crashed Chopper wreck would be different! lol
Five stars from me as its the most that can (legally) be given....
