The off kilter horizon distract too much in this picture. THere are a number of programs that allow for a quick and accurate correction. I know I often have to correct my shots to true up the horizon. Otherwise this is a beautiful view and very nicely exposed... Wish I was there right now!
Colors are equisite and composition is quite good although your horizon line is very slanted. Subject matter is compelling. Contrast is a bit too high and even though there is a small bit of window showing in the bottom right, I really don't feel it's enough to meet the challenge theme.
The window frame isn't clear enough in the shot. Plus this shot is extremely tilted to the left. The colors (especially the blues) are great however. :)
The bar across the bottom is distracting and there seems to be a green hue to everything below the bar & sudden texture changes that I can't quite figure out. I thought it might be part of a cement window sill but it doesn't carry over all the way, just ends. The whole image seems to be tilted to the left. Were you level or is it an illusion of an angled shore line across the water? All the pole tops follow it, so I think a rotation to the right would fix it.
Beautiful scene.
