From a technical standpoint, I see these flaws: contrast, lighting and cropping. Contrast and lighting are flawed in a similar way. The low light levels affects the overall contrast of this image. Like you mentioned yourself, it needs to be cropped to get rid of that white spot.
Aesthetically, it just doesn't pack a visual punch. I see the railing, the water, bits of the roof and the sunset but there isn't a main focal point that grabs my attention.
Hope that helps! By the way, I did not vote in this challenge.
Great colors and composition. The placement of the lamp shade is perfect. Use caution when there is a shoreline in an image to make sure the water is level - your's is not.
this is a beautiful image with some beautiful colors. I think there may be too much going on in the image though. There seem to be three separate focal points, the lamp, the fence and the sunset. Any one of these could be really interesting as its own 'part.' I'd like to see one focused on the lamp with a blurry pink sunset background perhaps.
