I have yet to cosplay, but when I do, the first thing i'm doing is probably cosplaying Samus. I'm a guy, but I don't give a damn. She's my favorite heroine, and besides, wouldn't it be a twist to see a dude under the helmet for once?
This, IMO is your best frontal shot of this Varia Suit Samus cosplay. I especially like how your eyes turned out in this photo. Unlike the other 2 photos,your facial expression gives this one a character to it. All in all this suit is amazing.
Ever thought of installing some extra tech inside it? For example, an mp3 player, hands-free headphones, a USB key, flamethrower (or at least a paint ball gun... or combine it into flaming paint ball projectiles), bulletproof vest (I wonder if it would fit underneath), fireworks (missiles), flashlights or even some kind of mechanism inside boots to jump higher?
OK, maybe that's too much, but the very possibility of building something remotely similar to the Power Suit got me excited.
