They look pretty good to me. I really like the one by Owen Harvey.
I know I'd love to be as talented as any of them, frankly. As Mr Harvey says,
Since they all seem to have mastered the art of sharp focus and not blowing the highlights in every shot, I'd say they were a cut above many a photographer. (Although probably the most important lesson I've learned is that blown highlights and soft focus are part of my artistic vision, dahlinks...

)
(The Cian Oba-Smith one is also a favourite, I should add, it's an excellent subject and the quality of the light is superb - London council estates do not normally look that, well, almost bucolic for want of a better word.)
