My favourite is #4 - a great combination of texture, colour, and contrast with the shadows. I see what you were trying to do with #1, but I think you need the curb to start further into a corner, and some way to make the 'background' elements seem farther away... shoot at a wider angle, be lower to the ground, and give the camera a slightly upward tilt to make the distance seem bigger perhaps.
great tips Plymer. Really appreciate it. I think you got what I was trying to do. It was first time trying this kind of shot, good for learning. I might get back to this place and try it again.
Thanks a lot
