Well, but trees will never be the same, so I would say that photos looking up a bare tree will also always hold some fascination.
But I do agree that your first pic here is quite strong.
You don't get to see the "urban angels" (others call them "flying rats" -- erm...) like this often. I like the DOF here, the urbanity is still visible, but the pigeon stands out... what does not appeal to me too much is the pink colour cast.
