Interesting pattern of the stairs and the shadows against the brick, which I rather like but it seems to make the skateboarder not stand out... Just looked again and part of what might be detracting from the skater is having things like a dark triangle of shadow in the lower right, part of an AC unit, I find things partway cut off or just the edge of something like the shadow in the picture to be distracting - maybe try some copies and some cropping?? I try to think about if I want something in the photo, is it adding to it or not? if not then I want it out of there! lol
The first one almost makes the subject seem like he's in miniature, interesting effect with the subject lighted and the scene being so foggy/misty. That one too I might think about the balance and if I wanted to crop the left side some so the figure isn't quite so far to the right in the frame. You seem to be seeing some creative shots.
