You've got a fantastic scene here. I love the way you have captured this, giving a sense of depth. Having said that, there is really a few things that needs improvement. The sky is totally washed out here, also you try increasing the sharpness, contrast and vibrance, which will certainly make this image stand out. If you're interested I can show you how this can be done.
Really a great shot. Should have waited for after the rains. You could have got more greenery to capture. If there is no rain in the area then yes you should have done some post work on the image. Even then without the post work the view is great.
I like the framing the trees create. A nice view of the dam and landscape in the background. As noted by others it could use some post photo work. Thanks for sharing.
