Well, of course I like the (fake?? ; ) stones (structure and colours are fantastic). Makes you wanna use them for your marble floor in your kitchen. ; )
But I have to admit that the scene itself looks too bright with laking contrast (like a photo taken with bad exposure settings). And the grass objects are good, though they still have a CGI feeling about them, dunno excactly why, perhaps it is the fact that they all seem very similar, with only two different colour-types.
Composition is nice, maybe just some more detail in the background and better exposure would make it perfect.
