That first one is really nice. The tree has a very symmetric shape. Beautiful. Will you get a chance to go photograph this same tree in the summer, too? With foliage?
I am no fan of your selective colouring in the last, I'm afraid to tell.
And something looks funny about that sky in the second, as if sky and townscape did not belong together. The street light is so clearly outlined... why is this so, I wonder?
