Yes, I was that Kikyo. You should have entered! The point of the cosplay competition isn't about the end, it's about spending thirty seconds on stage, saying "I look damn good," (then whining about how some bitch stole your soul and your boyfriend and stomping off.... or is that just me?) and then laughing and cheering with everyone else, for everyone else.
Do it at Otakon, just for kicks. ^_^
