Buttresses

I like this composition. It contains many interesting lines and angles. It's odd that the balcony(?) line at the edge of the roof is not level, but the trim line below it is! The roof peaks all seem to be at different levels, so it's difficult to say whether or not the photo is tilted! In any event, the textures, colors and angles make a very nice photograph.

The limits of Photoshop's (or rather my) ability to compensate for perspective distortion are evident here. Any attempt I made to improve the roof line and trim made the leftmost window lean downhill even more than it does. There's always more to learn, and I have not figured out how to get a curve out of a picture.
