Also, sorry for the long response time, didn't have access to my computer. Here is Seok's description in words and the pic that is the closest to copy-wright free I've been able to find to what he looks (part of the cover, actually). And for fun I'll throw in Selena's reference pic too.
Height: 6 feet, 2.8 inches
Weight: 170 pounds (very lean, muscular, and angular with his shape)
Hair: Black, short-ish, with spiky-puff bangs (kinda anime-like).
Skin: Pale, with a bit of sun-tan shade to it from working outside a lot.
Eyes: Dark green, with the Asian slanted eyes as well.
Face Structure: Strongly masculine jawline and sculpted nose (but he's no Micheal Angelo).
......Okay, sorry, Seok sort of got in my head, I apologize.
