Armageddon!!

So every year there's this comic convention that comes to my city. It's this amazing place called Armageddon. I plan to cosplay there! The only problem? I don't know who to go as!

I could go as: Edward Elric from FMA, my DnD character Eida, my novel character Asuka, an original character, or Lieutenant Hawkeye from FMA.

Edward is my preferred choice, but I have to do him well in less than a month. I'm a girl. I don't have the hair. And automail is very very difficult.

Eida would be amazing. I could get the entire DnD group to cosplay as their characters! There are practically no drawbacks, because no one but me knows what she's supposed to look like!

Asuka would also be awesome, but I don't have her hair. There aren't any other problems, except she's meant to be about thirty-five.

The original character would be built around this amazing white shirt and black waistcoat combination I found. I'd do it almost steampunk style. It'd be great!

I don't have Hawkeye's hair either. I pretty much have the colour but not the length. And her uniform would be a problem...

The reason I'm worried about the hair is because last year my wig looked terrible and I want to do justice to the character.

I'm going to enter the competition this year. It will (hopefully) be great. But I don't have much time left, whatever I do.
