the right is more interesting than the left, I think because you've overexposed the sky so much. I can see that there were interesting clouds, and blue sky, from the reflection but its all gone. Lot of potential if the exposure had been worked better - something to experiment with.
I have seen several photos depicting a reflection on a lake. This is the first, though, that give the reflection the importance it has to have due to the theme of this challenge (2/3 part of the photo is reflection and 1/3 are real trees. Good job.
