The file is very good. As an FYI, the ring is VERY large as is the opening for the finger. I'm a 300lb bodybuilder with thick hands...and it is too large for even my thumb. This is not a bad thing necessarily, just might need to be adjusted (easily) in the program before you run :) The details in the skull are great. If there was anything I would adjust (other than sizing) it would be to add a smiggin more material at the lower jaw connection on both sides.
