Definitely an unusual composition. My immediate reaction upon seeing was, "I like it." Yet when I contemplate it some more, I can't really break down why I like it, other than the attractive color and contrast and all that.*
I feel like the tree's branches are going to reach through my monitor and grab me, though!
Your photo is reminding me vaguely of a print of some 19th century painting I saw once, but I can't place it.
* I'm just now thinking, may be your photo is laughing at me, the tree saying "I'm the subject!" while that red door (and I don't want to paint it black) is slyly whispering, "I'm the real subject here."
