I like the use of black and white for these images, the last image shows how this could work, it misses the action of the other shots though, perhaps the first and third images could work well in B&W??

The first and last ones really stand out for me. The first being a fantastic action shot.

The last one in B&W really has that stuff that makes B&W photography so special. I especially like the way the shadows are included.

In most of these I think you have too much depth of field and perhaps aren't close enough to the action. A lot of potential here as you show in the B&W image that in my opinion is by far the best of this set.

I like the first two because you can see the skater's face. The b/w image really draws me in and makes me want to spend time just studying the photograph.
