Glutton for punishment, I have ended up making two battle maps for the set piece. This second one is slightly larger at 20x30" @ 300 dpi and depicts the ruined temple.

Exceptionally nice.
This would be even better if it were issued as a flip-mat with the building ruined on one side and in good condition on the other. I've had adventures set at a ruined caravanserai before, but it would also be fun to have a working one, and of course a caravanserai works as your original conception of a desert temple as well.
