Yes, I’d lose the sign. And is there leeway to brighten the water without losing the detail – e.g. by increasing the ‘Highlights’ a bit in LR? (May be tricky because the tonality is quite similar to the path behind and to the water surface. Do you have enough pixels to try cropping the bottom to just above the edge of the path so the ‘lake’ doesn’t show?)
I like the way the long focal length flattens the perspective so the people seem part of the water.
