I believe the system for ratings is setup for registered users, and it is they who will rate your skin, sometimes it doesn't seem fair, as I too have wondered in my ratings, but it is what it is.... don't take it personal, just keep plugging along with your skinning, and you'll reach those occasional five stars!

Do not done too much importance to the rating, believe me the only thing that matters is your satifaction personnel.Le rest will come with time, enjoy you in your work done and the best of you!
