I tend to go for the ones who look friendly, there's nothing worse than the stuck up ones who either turn their nose up or look to see their mates opinion before engaging you in conversation.
I don't tend to go for skinny blondes like most of my mates, if I have a type they are usually large breasted, big bum, brunette and often with black skin.
Saying that very few of my girlfriends look similar, I have only been out with 2stunners, and they turned out to be the most horrible women I have ever met.
Give me a friendly, fat bird any day. (Escapee ducks)
I have also had the 'Too nice to sh*g syndrom' I know you girls will find that hard to believe, but I have actually backed off from very attractive women when getting the vibes in that situation. They may be attractive, but they get damned annoyed if you turn them down!
