Rocking the Jean Grey Yellow Spandex costume. I particularly admire her headband, though it doesn't have the cheek panels of the actual costume. Really nicely done, though.
These guys totally win for their epic cover recreation, too.
Seriously, I could so get into cosplay. If I had a personal trainer, a babysitter, and enough money that I didn't feel I had to write all the time.
Especially that last. :)
