As stupid as it sounds, that might have done it. They are very particular about any part of a song being played over YouTube, etc. Not sure how to get it re-listed.
I'm also working on a Batman Beyond costume. It's not as detailed as yours but for the cowl I did go through the same people you did. I'm having a really hard time getting my head through the neck part. How did you approach that?
Still alive. I am the costuming director for the Amazing Arizona Comic Con so I've been busy taking care of that. Now that has come and gone, I'll be working on the mold tomorrow. In the meantime, my friends over at Jaze Cosplay Studios took the image of my cowl test fitting and made it into a fun movie poster.
