Hmmmm. Interesting. Quite interesting to say. There's a lot of amazing things you have put effort into this great work.
Like how you captured the details of the leaves, grass, clouds, and even the reflection. Just looking at this greatly reminds me of the location where I'm living in right now.
Even the colors add life to this picture I must say.
The ONLY part which I think you could try next time is to pay a little more attention to the reflection. All is good cept the very bottom right corner. Making it wave is nice, but the branches don't look like the one's from the surface (you know, thicker). Needless to say, you did an awesome job at this whole picture.
