Speed up your exposure and you can stop motion and bring your subject more into focus. The blured skater does have a nice effect in that it shows motion.
It looks like the skater (or should that be sk8r?) is your intended subject with no emphisis on the background. Look around at other locations. You can use your photo to make a more profound statement. As it sits, this is just a photo of a skater caught in midflight. Look for places where you might not always expect to find a skater (stay out of trouble and don't tresspass, but be creative).
Show me a shot of this skater jumping over a watermelon in the produce section of the grocery store.
Your angle is good, it gives the skater added height. Eye level shots can get boring sometimes.
