Awesome piece, it reminds me very much of =Ladyofspira's work, with that same attention to subtle details, like that overlay/mask on the water, just a perfect looking use of caustics, though you can't see much of it.
Wow. I've got to say that that water is looking mighty fine. I love the way it looks like its rolling onto the shore like that. And the detail on the terrain map is great as well. Excellent work, as usual.
