These are some sketches of how I wanted jet to look.
I thought the scarf, gloves and shoes were the most important parts of his design as they tie in with his everyday activities.
The scarf is used to cover his mouth most of the time, he’s spray painting a lot while on the move so it’s to prevent his from breathing in the fumes. Plus he’s quite anti-social so it fits him.
His gloves are made of leather and have rubber grip for when he’s doing parkour, also helps him not drop his spray paint can while he’s skating.
The shoes are specially made by his mechanic friend. They have a pressure sensor on the top of the sole that trigger a turbulent movement speed boost using pulse waves. They also have grip too so this is good for running up hills and even walls. It works well for him on his board as well as he can activate it to get a speed boost without pushing.
