Winkyface [EDITED]

You could of used the same frames but used a different amount of them and in a reverse order - so he re-opened his eye and mouth slowly (or quickly if you preferred) and that way it would of looped more smoothly while not having to draw anymore frames
Anywho...

I really like it and the movement the lines have, gives him a bit more life than if they were perfectly still - whether that was intentional or not, it works brilliantly I think .
