Mase,
Nice shots - Interesting that you converted them all to B & W...I would be interested to see the color versions.
Also, try shooting from the opposite side (get the look on the skater's face) as well.
See if you can blur the background to focus more on the skater & take a look at the crop I did. It really draws your eye to the action & not the other things in the scene.
All in all, a fine start!
Keep shooting my friend - fill up those memory cards & experiment with different settings, etc.
Best regards,
Nick
