Horizon needs to be straightened. Just kidding! The crazy angle adds a nice touch to this image. Is that a bit of sensor dust I see in the sky? Maybe not....
I love the tiled horizon. It ads a lot ot the image, to the different pespective. Thes sun was a bit high I think and might have condicioned the colors and heavy shadows. If the glass was a bit more green and the sky did'nt have those plots that looks like sensor dust it was a 10 for me. An 8 this way. just a hint: in photosho if you select only the grass with for example the magic wand tool and you copy it as a new layer then you can put the blending options in "dodge" and play with opacity to brighten the grass slectively. Play with the opacity so you don't get a unnatural look. 40-60 % used to work well.
