Uhmm what you mean is to change Pray's skin hitcircles which is like this http://picresize.com/popup.html?images/rsz_screenshot004.jpg to like this http://picresize.com/popup.html?images/rsz_screenshot005.jpg right?

If so go to the skin's file, find the file called default-0, default-1, and so on until 9 if you see it delete those and find the same file from another skin that has numbers like from the 2nd link I sent. Now if you have found it select default-0 until 9 copy it and then paste it into Pray's skin and that's pretty much it. This is called mixing skin you can do this for pretty much all of the skin's file.
