Awesome
the first shot is great, fantastic, I love it. The idea is great, and you pulled it off very well!
compuwar is right though, the background is the weakest element.
If you had shifted the plane or angle of the camera just a bit, to make the background all one color, like the green (grass?) part, it would be even better.
The 2nd shot is boring. Very boring. It looks like it was shot by a different person.
Not enough contrast, lighting is too flat.
