This is one of those photos where the bottom 1/2 is good but the top half really needs some work. It is a solid case for having the right tools for the job and a Grad ND certainly would have benefited you greatly with holding back that sky so it's isn't completely clipped and over exposed. that or HDR processing to get the exposure correct. The tree on the right is severely fringed with purple chromatic aberration, which can be fixed usually in post work. If you shot this in RAW which you certainly should be doing, you can try blending a couple different exposures together, 1 for the foreground and 1 for the sky. If you shot it in JPG you are out of luck.
I like the highlights in the bottom of the image on the trees on that shoreline, nice catch there, very nice.
Just watch your exposures and you will come away with a much better looking image.
