Well, I'm quite partial to photos of doors, which is why I like this photo for its very subject matter. Plus I like it for the colours and the light used.
If this were mine, I might consider cropping in closer, at least so much that the furthest left line of the parking space would no longer show. Personally I'd not centre it, I'd leave the door on the left, but I might put it even further left an get rid of some of the dark brick wall at the top.
The light falling out onto the pavement, along with the shadows of the ... what is that device called? ... and the two differently sized bins sure add to this photo a lot.
