A good solid image that is crisp, sharp and properly framed and composed - a technical success in every way although the image is a little too tall- it might have been more effective if the image had been cropped right to the edge of the top cloud. The cloud effect against the glass is nearly transparent and that is a huge plus in terms of artistic quality for this reviewer. Well done.
I like this a lot! There are some distractions, tho - the tree in the bottom right ruins the illusion that the building is part of the sky. Also, I think there's just a little too much plain blue on top. Perhaps cropping would make more impact?
Good - could be much better in my opinion if being still more abstract. Fixing the vertical lines, cloning out or cropping the tree below, centering the building, cropping a bit sky....
