8 - Like this, mostly for the shape/pattern of the waves on the shoreline, which obviously this size does not do justice to. Criticism; difficult, like to see those waves accentuated/used/enhanced more, but not sure if even a horizontal framing would do that. No idea how to adjust it, but as straight as the horizon seems, the reflection of the sunset on the water - if that was 'perfectly straight', may have made this even better in my opinion, hard to explain.
Very nice composition and colors. Part of the image seems a bit 'soft' to me, maybe it's just me. It also looks like there's a line about 1/3rd of the way from the bottom of the image, where a filter ended or something.
