There are some cliffs/rocks in the picture too, They are hard see but if you look closely you'll notice that they aren't that bad either.
Excellent color, but the stones look too "soft" because of the lack of hard glare at their edges.
Some AA on the edge of the cliff face would be a nice addition. Looks nice.
My only complaint would be the colors, the green and purple do not go well next to each other. Other than that, it is great.
