Nathan Fillion for IF 'Slither

I did this portrait of Nathan Fillion for the Illustration Friday Topic 'Slither'. He's one of my favourite actors and I'd been wanting to draw him for a while, since he was star of the movie 'Slither' this seemed the perfect oppurtunity.

It could look more like him, but I'm fairly happy with it and didn't want to end up ruining it by messing with it more!
