Wow very nice 
But is it me or does the neck look a little well.. Wierd?
I am the Blaster, I have filled the role of Tank, Controller and Defender
Sometimes all at once.
Union EU player! Pip pip, tally ho, top hats and tea etc etc
Nice one again. I like the expression of the main character.
But it's true that there are poke-through at the base of the neck.
And have you tried it with a floor ? I think it lacks a shadow.
Also, a definite improvement would be to hide the teeth/gums/inner mouth of the ghost.
And no, I'm never satisfied 
Here is another ONE .
One render, no postwork (well, my signature yes) and no toon shader!
