I would throw in another few pops of trees and bushes for the hills on the right, in patches (PF), and probably lessen the wave activity, perhaps even by increasing (or reseeding) wave patches, or add an extra (empty) surface shader after the water shader, mask by PF (large smallest area or soft color roughness), and smooth part of the water. You may also consider smooth reflection.
I would also dump a few trees on the left (or add a black simple shape to the masking to make an open corridor), to have some sunlight thrown through the wood onto grasses and beach on the left.
Airplane stripes are a 'nice' touch.
