Sparkle Swirl Brushes

This is my first set of brushes, so any suggestions on how to improve or anything like that would be great!

Comments and/or constructive criticism is much welcomed!

If you use my brushes on something that you've posted on Deviantart or elsewhere on the Internet, can you please let me know that you've used them . You don't have to provide me with a link, although I would love to see what creations you come up with
