SELFIE.
NAME. Erwin Smith
HEIGHT & BUILD. 6"1 ish, just over 200 lbs. He's pretty well built, lots of muscle from years of 3DMG use. He was missing his right arm though that's been replaced recently by Miranda and Val. He has some scars and no piercings.
DEXTERITY. Hahaha...ha...He can use both hands now, he was forced to learn to write with his left but he still prefers using his right again.
PHYSICAL DETAILS. Very striking light blue eyes and blond hair. He is normally always clean shaved aside from the few days of being in a funk after waking up after losing his arm where he looked all scruffy.
CLOTHING & ACCESSORIES. Erwin's personal style is military, really. He's not used to dressing himself. He's used to wearing military uniform- the brown jacket, white shirt, stylish bolo tie, white pants with brown boots complete with the 3dmg straps or a variation on that with a longer coat after the loss of his right arm.

Otherwise he tends to dress pretty simply, button up tops and slacks. He likes sweater vests and socks with sandals here or suits with ties for work.

PHYSICAL MANNERISMS. Erwin still carries himself with a military bearing-straight backed and rigid. He doesn't tend to relax easily, he is used to having to act a certain way. There are times when he can be a bit more expressive but those are rare moments. Also, don't forget his creepy smile.
VERBAL MANNERISMS. Erwin's well-spoken, clear and very strong. He has a great public speaking voice (even if what he has to say isn't all that great) and can command the attention of a room easily. He has a deliberate way of speaking, he will say what he has to say and that's all, he won't ramble on for the sake of hearing his own voice.

looking into Erwin's mind would mostly be terrifying. He's always scheming (fearful scheming...) basically arranging the world around him like pawns.
