@YoItsNotWhatYouThink try searching by the feature you would like people to notice first, like the grey/blue/brown/green eyed g/b, or hair colour or styles, mybe their attire too. then, besides google, u could use tumblr or pinterest hihihi...they're the only ones I use lol
oh! and adding like hot or beautiful in front of the feature is a great help too :D
