The composition is really nice.. the bit of grass on the bottom and the trees at the top being visible and less visible in the distance with the light crossing through the whole picture makes blend the 3 elements amazingly together.
The overall presence of green makes it the last perfect touch i like so much about this picture!.
It has a very good depth aswell, I think its always nice to recognise deph in nature photograohy.
The only minor negative point is the slightly blurred leafs, being the last missing thing to this photograpohy to be pure perfection.
very Very good vision and work.
