I feel the contrast is pretty heavy there.. but if this is really untouched, then that's quite impressive.
I like the range of colours and how it all feels quite natural where they are concerned. It's awesome that you've got a bit of rock, water, land.. trees. Lots of different kinds of nature here that make for an overall interesting piece.
I feel that you could have moved the camera higher a bit, possibly.. but other than that, it's a really nice piece!
