Agree with Sai, some details which I'm not very sure of is missing and transparency counts as colour.
I believe this is 8 colors including transparency. Not 9. it's an interesting approach, but I feel like it kind of lost some of the "troll-ness" to it.
Haha, cool new look XD
And neat use of AA and did I say that i like your outline?
It kind of seems like you butchered the troll face trying to make it seem more anantomy perfect.
It doesn't really feel the same but it's a decent piece nonetheless.
