Beautifully framed. It is very nice that the foreground sihouettes a well lighted building. The dark framing makes the bright building stand out even more. One of the best images in the challenge.
Your frame is shaped well around your subject. Your subject is interesting and against a nice sky. The light on the top half of the building shows it's form well. This is dood shot all round. My only pick is the bottom half of the building being in shade (how avoidable that is I don't know).
Trees and leaves do make a pretty frame. Using them as a frame also explains the dappled light on the building - which could be a fault in other circumstances.
