I really don't like it.
Your 2nd one has terrible light source. It's on the wrong side of the head, it's too strong, and it's too small.
The left side is boring. It's blurry and gives it the feel that there needs to be something there.
3rd: Don't use displace and not bring down the opacity. It looks tacky. Work on blending and this could be decent.
4th: Someone learned about c4ds. Don't whore them like that. Work on blending.
5th: Background is terrible. Work on blending.
Now don't get me started on the text. Please, save me the time.
