This is GORGEOUS! I totally love the concept, the idea is so great!
The only thing I would have tried to do differently (just to see what might come out of it) is... soften the base of the tree - the base of the reflection, of course - a little, and erase the trees on the left so that the "major" tree and its reflection stand out, without any distracting object around. Mmh... My explanation sucks.
Anyway, it's amazing as it is, you have a vivid imagination!
