Overall this photo is just a little too soft. The boat is not sharp enough. If the boat were sharp and the backdrop a little soft, that would've been much much better. Looks to me like the focus just wasn't quite in the right spot. Very nice scene, one to go back and try this shot again, with maybe a little more light.
Did you try other angle of the boat, such as having the sunset/sunrise directly behind the boat. Currently the boat is almost to far right and my focus area tend to more towards the sun.
beautiful colours here. I think the composition is great, although I would have prefered the boat to be a bit more to the left, as the main subject of the photograph.
Fits the challenge, nice soft colours. I like that you framed the boat off-centre and (whether it was or not) how the sun seems to shine from behine the building.
