They look similar, with the F one being more smiley. But according to what she herself says, off camera, she both looks and acts more like this last one. I remember she once showed a clip of herself shopping, and she wasn't all made up, and she did look quote different, and could fit that last one.
I don't think it's always in exact face shape, but in general expression. Mia Wachichowska (Alice in Wonderland) is pretty close to Socionics EII/INFj (Fi-Ne.. I think some are MBTI INFP or INFJ). So am I to an extent. Although I have a goofy ENFP face. She's like this a lot though, even when she's not affecting that look too much.
Rose McGowan is probably ESFP (the Socionics website has her as Fi-Se though.. but she doesn't look like the ISFj portrait).
ENFPs I read on one site are hard to spot. Like it's more about the general goofyness in the sketch, rather than a literal portrait. I've seen Olivia Munn tossed about as a possible ENFP (and she acts like it), but it's not that obvious.
In some cases, it's very obvious. Angelina Jolie is a blatant ISTp.
I think Mira Aroyo from Ladytron is ISTp as well.. she seems to not diverge from this much.
The other confusing thing I've heard though is that sometimes people in the same quadra can resemble each other. Might be a "reason" why some couples look like they're slightly related at times. Have you ever noticed that?
