OMG Mark! lol...
Uhm... first, Elton John didn't have a Candle on the Water, He sang about a Candle in the Wind. I'm closer to Deep Purple's Smoke on the Water. Only for me, where there's smoke, there's fire.
About the grain mill... Mark, I already have one, on of yours, actually. Is it too small? I probably need to make it bigger, or use the other one... but it's that square building that is SUPPOSED to have a glow and shadow on it, but doesn't... near the right outer wall close to the fields. I'm using one of the Vyntiri windmills.
As for the height of the island above the moat, I thought I had showed that the surface of the moat is much lower than the island. I will play around with the effects a bit more, to see if I can get it to look deeper.
