Sorry Kain and Terra wouldn't go good together but that's anice costume. If I had your costume I actually would wear it whenever I go out, like to the mall or drive with on. It's that kind of thing where you rather wear your costume and just leave it on...forever if you want FFII or FFIII to become real.
I love how though they are from different Final Fantasies, you two have managed to make them look like they come from the same one. Between the background and how you two act as a couple, it just seems like you make it one Final Fantasy.
Squall's outfit is AMAZING! (Okay, and it makes more handsome than he all ready is. Blue looks good on him. I love the face being half-covered although he must have been blind!)
