I really like the warm and cool tones combined on this. I also like the gentle angle of the street rather that it being straight which would have been a less interesting composition. I'm a fan of "happy" compositions with very little tension so the tree doesn't work for me here. It creates a hard break in the flow which is a distraction, but again that is just me and my taste...not your photo! For my taste I would love more emphasis on the arching window with bars and the great bricks.
Beautiful and intriguing image. I love everything about it: the brick wall, the arched window, the leaves, the tree and shades, the side walk and road...
I like the composition, diagonal, rules of third and so forth! I like the arched window, it makes one wonder what's down there. Also, the cropped-off tree on the other side looks good because you used shadows for the leaves instead of actually showing leaves which could have made this image too busy, perhaps?
I also like the strong blues and complimentary golds. A nice, mysterious image!
