The difference is relative - in a bar full of women who were loud, flirty, and playful, Anna was the wallflower that blended into the background.  Another clue was the guys had those "spoiled frat boy" jackets, meaning they're exactly the type to ignore a wallflower.  Anna made a poor choice introducing herself to that table.

I haven't really tried casting Anna yet.  Actually I haven't really tried casting any of them permanently - I've made comparisons before, but they change often.

Anna was designed both physically perfect (because it's actually more difficult to create a physically flawed android) but not too far above average (because she's a military creation, not a sexbot).  I didn't say before now, but her deep blue hair was to give her character, because otherwise her lack of physical flaws could actually make her less believable as real to an observer.

But in a pub full of outgoing partiers, Anna fades into the background as someone who's quiet and nervous.  Ironically, if she would have smashed the table as her first instinct said, she probably would have stood out and gotten a few phone numbers for the trouble.

This also reminds me of the "hiding in plain sight" theory.  Lara Night is very famous at home, and likely somewhat famous in Paradopolis.  Hardly anyone bothers her though because a) she doesn't wander Paradopolis all the time in costume, and b) when she does go out she looks like any other attractive blonde, and purposely tries to do so, going alone and trying to blend in to not draw attention to herself.

It's similar to seeing someone like, say, Ali Larter (who I've compared to Lara before, just not here) in a cafe in L.A., drinking coffee, wearing a baseball cap pulled over her eyes and very little makeup.  Sure a few people might recognize her anyway, or recognize her voice - something I can do myself - but in general, most people would just order their coffee, move on, and ignore the blonde sitting at a table in the corner who looks like thousands like her in L.A.
