so, errrr, who's Agnes?

Hmmm, not bad. I like the facial expression.

The chin looks about right, eyes look okay. However ,the forehead looks a little too big, and the neck looks like its scrawny and tilted backwards.

I think if you moved the right line of her neck a bit past the centerline of her chin and made it a little more vertical, that should correct the problem with her neck.
