It's just a roof of a garage, looking straight up, close to the wall and cropping out the brickwork.
I'm assuming the white areas are the cropped out bricks? Might be worth running a 'blur' brush along the edges to soften them a little. It looks rather harsh. While I'm not keen on the image, there are things you can do to it to practice.
Where the brick just nasty? I'd be interested to see the original.
