thx! i just drew the bag with pencil, then colored it in with marker.Then i went over it with colored pencils, paying very close attention to the highlights and shadows. I used the 24 pacc of Prismacolor colored pencils, a white gel pen,and some random crayola markers LOL. If u wanna recreate this, just know that theres shadows on the sides, and for every crease, theres a shadow and a highlight. And also, theres some really really bright highlights/glares near the top of the bag.
