My girlfriend accidently looked at the skulls and said that either the top skull should be increased in size, so the
text in the eye can be aligned easier, or the lower jaw should be shrinked. The alternative is shrink the lower one
and increase the size of the top one until they are somehow of the same size.
Makc, i would say you just increase the top skull and your're done, since changing the size of 2 objects is twice the work.
I think that it safes you time and in addition maybe when the top skull is bigger, you have more space to move for the eye-text.
If you feel to re-align the eye-text again, you can do it but you don't have to. I'm completely satisfied how it is now.
