Thanks...

The fields are going to need a little more work before I'll be satisfied, I had to shrink the pattern down a lot, otherwise the plants were HUGE! I'll probably drop them out of this map.

Have to admit I "cheated" on the crenelations, they are images from the Dundjinni forums, so I cannot take credit for them. I just added a "toned down" texture to them.

I swapped out the frost texture than added a few more strokes with an airbrush set at around 30-40% opacity. I'm fairly happy with it now, though I'll probably tinker with it some more.

Shadows are always something I struggle with a bit, is it to much, not enough, to dark, to small, to big, etc. etc.
