I would second what MadSquirrel has said but with a twist. Either the sea needs to be more active (currently it seems to be in slow motion) or the coconut needs to be slower in its response to the weight/impact of the bird. The same IRL physics applies to both the wave motion and the motion of the coconut.
Minor detail, there should be a spreading ripple around the coconut both after landing and after takeoff.
The sea seems to be tilted. That may be reasonable in terms of the larger scene, but it doesn’t work for this small excerpt.
The foreground bird is not highly detailed but its motions are very good.
I hope this helps.
Good things that don’t need changing:
The music is just right, in my opinion. It is cheerful and at the same time not overly so.
The birds circling in the background; I really like the fact that they form no obvious patterns. (Minor quibble: They aren’t beating their wings properly with respect to their position in their flight paths.)
