The decision to fill the frame with cloud was a good one, and leaving a small amount of detail (birds etc.) in the foreground works well.
I do sense that this shot has a blue cast to it - probably due to the time of day. As a result, the clouds are toned and the sky doesn't have as much punch as it may have had when you looked at it. It would have been a good idea to either use a polariser, or simply a UV filter to block that haze. In post-processing you could try adjusting the levels to bring out more whiteness from the clouds - that may potentially make this shot even better.
As far as exposure is concerned, a deeper DOF would have been good. I'm guessing that you took this in program mode. The foreground does have interest, and could be sharper, and the land on the horizon is quite hazy and indistinct.
What lens focal length did you use here? I think that this one is a good candidate for a wide angle lens. What you could have done, and indeed can try in future, is to take the shot from a lower angle using a wider angle lens and smaller aperture. This would give more drama, and keep more the shot in focus. I'd also suggest going closer to the water's edge - that's the most dynamic part of the whole scene so you should try to make more of it. If shooting near breakwater, it's usually better to take the picture when the waves are receding as they have more interesting shapes and patterns at this point.
All in all, you have a good starting point here and this subject has a lot of potential - especially if you have an opportunity to go back and try out a few of these suggestions.
I don't get the title, it's a pretty picture though. It doesn't convey the feeling of infinity. I think it's because I can see the land on the other side and the title is telling me to look at the water. Hope you can understand what I'm trying to say.
riiight.. THERE! you can see it on the lower left hand corner. oh wait.. no, that's just dirt on my monitor.. i dunno.. where DID you leave that damn bottle?
