The large dark are on the right is a little over powering. May a vertical composition just inside the pole in the foreground, keeping part of the dark, but not so much??

There are interesting elements in this shot. The diagonal shadow coming across the "window" gives a really graphical picture. But I agree with Beamer, I think the right part is really too present and doesn't add that much to the composition, could have been cropped a little no? Nice light!

Agree with the above two comments about the right hand side, but the rest of the shot is fantastic.. I love the contrast between the dull foreground and the colourful background through the window.. Very nice.

Agree with the above comments.
Details and focus are spot on other than what has been mentioned prior.
I really like the blue through the window as it really makes you wonder what is there!

Thank you all for taking the time to comment. I actually tried a tighter crop but found it lacked in depth as opposed to this one. But I'll have to agree with you on the unnecessary dark space. As for the blue outside the window, it's...the sea.

Nice colors. The dark area (too large for me) could be reduce by cropping the picture on the right up to the luminous post. The resulting more square frame acting as an echo to the square frame of the broken window?
