Thanks for your comment! You're lucky to have such a beautiful library in your town. It must be fun to sit close to the windows and read a good book. I love blue glass. It's such a pity we couldn't use the perspective correction tool for the challenge, don't you think?
BTW, what made you think my picture to urban landscapes was mine? I didn't post it anywhere else (not this time :)
This is a nice library - lots of artifacting/diagonal lines in the curved edges of window and building, and to a lesser degree in the square roof to the left, though.
Good composition. It looks almost abstractive - I like that. Consider using polarizer to cut down the reflection in the windows. It could have been neat to see through the windows inside the building (which with polarizer is possible). The sky is greatly dramatic. Your image is a bit pixelated - maybe too much compression?
