Alright, description time:
Character 1
Tristan Wright
Face: he has rather wavy, blonde hair that he wears in a side part. The sides are short, and up top is longer so he has a fringe. His eyes are grey. He has a very pretty face tbh, although that's also because he tries hard to be presentable. Rather high cheekbones, decent jawline - not on the level of a supermodel, but he's definitely getting up there as an 8-9/10.
His expression is usually rather neutral, although he has a tendency to think harder about things than is good for him - so he gets that ponderers frown/daydreaming distant stare.
Body/clothes: he is 1m75 tall, and not very special body wise since he spends most of his time studying. He's neither fat, nor bulky nor thin. Just super average. Clothes wise, he nearly always wears a suit: necktie and cufflinks included. He's aspiring to become a politician, so he definitely has that slightly neurotic tendency to overdress.
Character 2
Hibiki Yukimura
Face: Hibiki is Japanese, obviously. He has a rather round, boyish face, usually smiling, smirking or otherwise grinning to get away with some devious plan he has just used to get on Tristan's nerves. In general he's rather playful/'fuck the rules'. He has black hair, about cheek to jaw length, which he doesn't really do much with. His eyes are black/dark brown. He has bad eyesight, so you can draw him with glasses if you like (he has those square, dark rimmed ones).
Body: he's 1m65 tall, and built rather slender. He's not buff, but he has some muscle tone (it helps that he's skinny). He has a very punkrock style of dressing, wearing black all the time. He doesn't wear suits or anything formal at all. Instead he's one of those people who can pull off effortlessly looking stylish in plain clothes just by having the right combination. (Adding accessories like beanies, bracelets, belts etc.).
Hibiki is basically a combination between punk, cute and a prankster.
