I agree with what the others say, and I would also add that a slightly lower camera level would work better. The high standpoint of the camera from the sea seems a little unrealistic, unless you could show a high cliff edge in the forground, as if the camera is looking from there instead of from the sky. This could give the impression of the other side of a bay area.
I like your other improvements so far.
One other addition to remember in any scene, is to give the viewer something to focus on, hence the mention of too many ships. This would work of course if one of the ships looked different in some way, or was doing something different at least.
Keep em coming, interesting so far.
