Reflections

In my opinion, the image is below average. The sky is completely blown out - I don't know your technical details, but next time you could try a smaller ISO setting or a faster shutter speed to avoid blown out highlights.

I find a lot of the branches close to you block the actual reflection in the water. You could try finding a place where there are no distracting factors, or if that's impossible, try at least to minimize them.

I hope that gives you some ideas. Keep experimenting!
