Pure awesome, really. Found over at Geekologie, who found it elsewhere, as these things tend to happen on the internet: this amazing Big Daddy/Little Sister cosplay was taken at the Georgia Aquarium by Harrison Krix, who made the Big Daddy suit and Little Sister ADAM syringe. He’s also IN the suit, and that’s his fiancee as the Little Sister. Creepy.
