Great idea! Just 2 things: the stones should be thicker, and instead of faking it, you could have imported the grass edge from the foreground stone to the edges of the others.
(You still can...). GL author.

haha love the idea!

Moving stones!!! nice work Add thickness will be much better.

AWESOME IDEA (to thicken the stones easily.. just duplicate it and lower the back layer with nudge.. repeat and it will be plenty think in no time... other then that.. EXCELLENT WORK

Love it!

That's the definition of "simple & effective - less is more"
You could follow Driven's advice, pay attention to perspective though, the further the stone the thiner it is.
Also fix that grass like CMYK said and clear those masking problems.
