I have a feeling this guy stole 2 of the images and made the third one himself, in a very stuffty manner.
This is the face he made (thumb): Not even transparent:

This is the face in the pack I should declare stolen; notice the better quality and transparency.

Excuse the "sepia" style, I am using Windows Image Viewer but there's something wrong with it.
(And I didn't upload the pictures, pictures were taken dirrectly with Gyazo.)
So yeah, I declare O.P. a stealer, seeing 2 of the faces are stolen (The second being just a small edit of the above, with an red eye) and the third one being his "custom" face, which is eitherway, stuffty.
