A new try: are they nice or interesting?

I shot these pictures today... It was sunny, I decided to have a walk close to my work and take some photos...

I tried something, but I still get confused about them. What do you think?

I've always been attracted by taking curves, lines to enhance deep into my pictures, or create some kind of effects, and I wanted to start a new thing: our urban infrastructures ... take pictures of squares, cubes, blocks...

tell me..

what i like in these pictures, it's the shadow on the left half sizing the steps...
