I think Seifer can be very hard to portrait but you did a very good job! The costume looks incredible and very detailed, also the mood of the picture captured his personality very good. Is that a wig? It surely doesn't look like one. And I LOVE your gunblade!
I think the mood of this photo captures Seifer the best, personally. Lovely cosplay, you make an incredible Seifer. He's one of my favorite FF8 characters. xD You'd make a dashing Lestat as well, I think.
