A mixture of Ellen Ripley (the fictional character played by Sigourney Weaver), Olivia Wilde and Vin Diesel.
"Wait what?"
Yes, you heard me.
Ellen, because she is a strong and intelligent woman who has no intention of being on the same level as those women with bleached hair, tight jeans, a big-ass belt, overkill eyeshadow and a white jacket with fur on top.
Olivia Wilde, because of a few physical trademarks I like, mainly her hair, voice and lips. Might as well picked an other woman with attractive traits, bu this one is just off the top of my head. (i.e. the perfect female, in my opinion, would also be attractive - don't know if that makes me shallow)
Vin Diesel, because he's the kind of guy who does typical 'nerd/geek'-stuff like playing video games, being involved with Dungeons and Dragons, etc. - but I bet no one would have the stones to call him out for it. I'd be nice to see that in a woman as well.
(on a side not, the man may not have had a lot of successes recently, but dammit, he still put down some nice performances in Saving Private Ryan and Pitch black - and as the voice of the Iron Giant, of course)
. I mean, who would want their best friend to act like a lover?
