I'll have to reject this mainly because of its overall quality.
The first problem is how you tried to replicate the reflection / sunlight effect in this background. It looks poorly made, because the fake HDMA in the sky "breaks" constantly. Also the quality of the trees is very odd. Also, why there's some white trees here? While it's a nice attempt, you should be more careful when trying to replicate photos. Realistic graphics are a great amount of work and so, I speak them to be at least convincing.
