1st and 2nd pic focus seemed to be more in between on environment and skater rather than singular unit, making the entire picture looking a little bit "blurry'
3rd & 5th pic is very obvious that it was edited, look at the wall.
4th pic is too intense--overexposure?
6th pic same problem as 3 and 5, look at his jeans.
im learning about photography as i go along too, so don't pay too much attention to my comments.
