While some may argue, I like the spaciousness of the photo, as it gives it a feeling of standing out a bit, and a lonliness.. But yes, the focus could have been better (If it could have been helped, that is) and this is just my preferrance, the photo looks amazing as it is, but if only the sky had been blue that day.. Blue water would have made it better in my eyes.. But color itself is nothing to judge..
The composition of this, and the reflection are super. Such a shame that your focus is rather soft as this could have been a magnificent image had it been sharp.
There are some things you could do (disclaimer: of course this is only MY opinion)that would improve this photo:
a) crop it so we're a bit closer and so your subject is in the lower right hand "thirds" point and
b) use curves in PS to improve the haze and make it pop more. Possibly even tweak the colors a little, too.
Because this is not in focus - and I can see why, you probably had to zoom in a lot - it is not pleasing to the eye, I like the idea, and it is very cool too.
Really cool...nice reflection. Interesting how there is no contrast between the sky and the water so there's just this island and bird in the middle of nothing. I like it.
