First off let me say that I have had experiences of judges just dismissing a costume outright, and when you have spent alot of time and effort in a costume it really makes you feel like crap. The puckering of the seams is rather unfortunate as it takes away from your electrical work.
My advice for the next time you enter a masq is to keep talking. Dont ask the judges if they want to see something show and talk. Make a list of thing that you think are important about your costume and keep the description short. If you have a bunch of electronics that can do cool stuff skip over minor details and get to it first. You should practice for going on stage, posing, and selling yourself to the judges.
