Now that the whole submission thing is over, I am worried over how things are going to turn out. I worry that the community will pick only whichever ones have the best art rather than the costumes that mesh well with the content and themes already present in Terraria. See, with a lot of the submissions, no offense to anyone, I just think that they were made to satisfy whoever created them rather than being something that a lot of people will see in game and say "yeah, I want to wear that". I hope ReLogic chooses wisely with whatever they're picking, and so does the community with whatever people vote for most.
Of course, mods are always there if whatever you made doesn't make it in!
