I think some will say that the horizon should be level, but as the jetty is the main focal point of the picture, I think you have got it perfect by having the front of the jetty level instead. A great picture with good colour effects too. Good work Adam!
It's a beautiful photo, my only negativity would be the dark spot in the top left corner. I think it might be a bird in flight, at first I though it was dust on my screen :-]
Might want to take that out. It' will boost it from a 6 to a 10 and on and on.
