As in the attached photo, rocks by the sea stand out too much, if something can be done with their colours, lighting and in addition a way to make it stand out less and show that we are at sea is to make them look like beeing wet ( darker colour, as they were in contact with water since much time).
and if ever polycounts allows some space for work on rocks, increase the numbers of polygon, to make the shore look more fragmented {F16733}
