A well timed capture ...
Really nitpicky, but the man in the left background really shouldn't be there. Also there is something that seems to be a power line above the trees that could be cloned out.
Dunno, I reckon leave him in. Is it a crop? If so, crop it again & leave all of his right leg in the picture. There'd be people watching him. You look at the image, are drawn to the skater then your eyes are allowed to wonder down to the lone spectator.
only thing that would make it better IMO if it were shot during the golden hour
Makes sense but it obviously wasn't a "setup" shot. You took the opportunity when it presented itself.
I like, but could use a little saturation. IMHO
For sure. You could even try "replacing the sky" in Photoshop!
and also, post the image a big larger next time. It's a bit small.
