This is just a mash up using Gimp to demonstrate that the head sculpt might not be as bad as it first appears. I've never tried any painting on 1:6 and at this point, I have no idea if my painting skills can turn this into reality. It also looks as though Mike Dela Paz has done a repaint on her eyes already in the above pic (and made her lips more red) so the 'raw' figure might be more challenging. He's definitely done a good job styling her hair, which also helps.
I'm going to have a play when she arrives to see if my skill is up to the task. If I think it's doable but not with my level of skill, I might just commission a repaint.
One thing I did notice was that pasting eyes and mouth onto this sculpt can make it look more Famke, whereas pasting them on the X2 custom sculpt doesn't. So the face shape, nose, and eyebrows on this figure are closer to the actress. The custom sculpt, while far better in terms of look, doesn't seem to have the right nose and jaw-line.
That said, even before the re-paint, you can see shades of Famke in the right side partial profile. I'm not 100% convinced that this is reflected from all other angles. I'll have a better idea when she's in hand. My work to date has been on 6" and 7" figures and 25-32mm gaming figures where the likenesses are more cartoony so, while I think I might be able to improve the official paint job, which butchers her likeness, I think that I might not be up to the task of 1:6 painting to really bring out Famke. Here are two more Gimp mash ups.
It looks to me that the shape of the eyes are not too bad but the over-sized iris is just wrong. I think maybe painting in a slight eyelid, slightly heavier eye-liner, de-accentuate the lip interaction with the fultrim, widen the mouth and maybe plump out the lips. The pics below have open mouths so they are not overly helpful.
