Can I say that that is extremely well done?!
Is the map in the background a CC2 map texture? Very cool as well!
Do you have any plans to sell that compass rose model? I have an extremely long running campaign that I would love to use it in, and I think I would use it exactly as you have envisioned it. The campaign is a sort of globe spanning treasure hunt so this would be an awesome artifact for the players.
If not, that's cool too, but would you mind if I "borrowed" the picture to show the players?
