if u add highlights first its gonna be hard to outline it exactly where the white is and u can always just go back with black and outline whatever u messed up anyway

always plan where you wanna go and paint your piece. usually check locations through the day. i always have a specific spot in mind when i go out. check for amount of traffic at night, is your location accessable via foot, do you need take caution for pedestrians. spots without a path for pedestrians is always better. so highways where's no pedestrians is pretty good and cars can't stop for you. stay safe tho. no risky actions to get to places. take only things with you that you really need to stay mobile. cover as much as you can from your body asoon you get near your spot. (not like me in this video). i had a hedge behind me so i had good cover to the street. also this wall belongs to a garage which leads to a dead end. so no traffic or people near me either. perfect spot
