Changed colors of the ocean

From the rocks on the bottom right corner, moved up to the ocean and changed the colors from purplish blue to a-little-green-tinted blue. Since I mixed quite batch of the color, refined the tree/brush shapes as well on the right edge on the island by putting sky/sea holes between them to make them more natural. Now I'm go back to the island's tree&brush shapes to complete that part. This might be the last update of this painting before finishing it.
