The only drawback which I feel like pointing out is the originality, which wasn't exactly shown in this photo. However, talking about the impact, I have to say that you managed to give your photo a huge one. Not only that the composition was off the hook, but the colors played an important role as well. I loved them, they were really bright and nicely saturated and gave the whole thing a warm and cosy atmosphere. Another nice aspect is the sky, which is simply breathtaking mostly because of it's extraordinary and spectacular hue. Last but not least, I love those ducks, they animated the entire photo. Great job!
I like the colours, and anything to do with jetty excites me.
The colours are beautiful, but i feel you could have got more out of the dynamic range of your camera... by shooting in raw and popping up the dark and midtones.
Because right in the center of the image, the colour dies into the darkness.
Though rules are made to be broken, The composition would have been better if you had adopted the 3/4th rule. One common rule always helps... if you shoot at the height of the eye, which is the way everyone sees the world, you have created a common image... which in many ways is mundane.
but say if you got on your knees, on what seems to be a lovely beach, shot the picture from a lower angle or different perspective, it would have a great impact on the image..
Last but not the least : Please use a tripod. I personally hate carrying it around myself... but it does help the images... it gives you the freedom to shoot at low ISO / low shutter speed.
With low shutter speed, you could have added the motion blur in the water, which would have made the picture look like dream world...
Also using the tripod, you could have exploited the small aperture, say f 18, and got most of the image, from the jetty to the clouds in sharp focus.
