In the middle of an ancient stone ring?? There has got to be some sort of "Curse of the Celts" low-fantasy scenario to be had from that!
The church looks lovely, and I must say it blends very nicely with the rest of your terrain. Just the right "chromatic ambience" (yes, I know those two words together are nonsense) for dark ages Britain.
Adrian's Walls is too expensive for my budget, and I prefer to paint my own terrain anyway, but one thing I appreciate about Adrian's Walls is that the webstore displays the products in photos that "set the scene" with figures and other terrain, showing the terrain pieces "in action" as it were. It's much more inspirational that way. Ainsty is another company that does this. I sometimes browse webstores like Adrian's Walls and Ainsty just for the inspiration.
