Good choice of background "subject" for this topic, since the the main subject will necessarily lack detail. Since it's so close anyway, I might try a square crop, making your basic shapes radiate right out of the upper-right corner, instead of just off from it as it is now. It should put/keep your shadow pretty close to the 1/3 line on the left.
The Depth of field is off. The foreground looks much more blurry than the back. The affect on the brain believes it to be too blurry. Great color though. I like the shot.
Great colors! Simple concept, nicely done. The lines pointing towards the upper right make it an interesting composition. Minor nitpicking: the grass and the horizontal line at the bottom are a bit distracting.
