Blake Walker might be somewhere around 6 feet, but it's damn hard to tell because he slouches. Long-limbed, and with a wiry sort of fitness to him, he has that odd sort of relaxed demeanor that's always simmering with movement. His face is sharp-featured and has some hardship lines that make it hard to tell just how old he is. His hair is somewhere between brown and auburn, and his eyes are a cold sort of green. He dresses basic: french-tucked button-downs with the sleeves rolled to the elbows, jeans with the cuffs rolled up, and hard-souled leather brogues. In cooler weather he adds a black wool coat that's definitely seen better days.

His pride and joy, however, is a black painted 1967 Pontiac GTO, which he drives to his semi-regular gigs playing jazz piano in clubs and bars and sometimes high-end department stores.
