not terrible
A bit of criticism. Either eye, when viewed without the other looks fine, but you've got them kind of out of sync with one another. If you dropped the eye on the right ( her left ) just a smidge, it'd look alot more even. The on on her right looks great by the way. Her hair looks a little flat right in the middle. That could be the original photo for all I know though. The hair could use a bit of detail work, but I understand not wanting to go that extra mile. Hair can be a pain in the ass.
Beyond that, and this is the part that kills me. It doesn't really look like her. It does look like someone, just not her. I say that kills me because that's the main problem I have when I do portraits. It looks perfectly fine... except it's not the same person.
The rest of the body looks great, the mouth inparticular looks nice. Good job on the lips. But I gotta say, the eyes being off kills the whole thing for me, and since that's naturally the first thing i'm drawn towards I notice it's off before I begin to see whats right about it.
