Witch one? (Help)

I seriously can't choose witch of these four color pallete's so could you guys help?

Going Right to left:

Original: The first color pallete I did. White hair, Yellow eyes, a black shirt, a dark purple jacket and gray pants.

Mistake: I was messing around in Paint Shop Pro 5 wondering if I wanted to add anything (Like a Magical Aura) and I clicked the Brightness/Contrast button and messed with the slider thing and ended up with 'Mistake' He still has white hair and yellow eyes however there more of a pure one color yellow unlike 'Original', his skin is lighter, His shirt is now a even darker black, his dark purple jacket is even darker and his pants are now the same shade of black as his shirt.

Test: After 'Mistake' I wanted to do some test's. So I did more messing with the Brightness/Contrast He still has white hair, His yellow eyes have went back to how 'Original's' looked, his skind is a little darker, His shirt and pants are the same as 'Mistake' and his jacket is just a little darker then 'Mistake'.

Dark: After 'Test' I did another and ended up with this much darker color pallete. His hair is now gray, and his eyes are a darker shade of yellow, his skin is noticable darker, his shirt and pants are now pure black and his jacket is so dark it almost looks black.

So the question is. Witch one should I do?

Original: 1
Mistake: 0
Test: 2
Dark: 1

Also! I gave you a hint as to what he is/what he does. can you find it? can' you guess what he is/what he does?
