I honestly wonder how many true artists are in here. Nonetheless the costume is original as a final piece. It's well rounded and balanced. There were alot of costumes I saw that were VERY busy and or themed outside of the BnS realm. I don't condone cheating in any manner but as an artist myself, I condone 100% the use of references to create an original creation.
What most people are doing is nitpicking at elements of the outfit, not the outfit as a whole. If you want to be nitpicking, I am very certain someone can find something (small or big) about every single outfit and
