Hey there!
So this sketch is about a Tailor that works with men's suits, I probably should upgrade a bit his attire as well, maybe instead of an apron he could be wearing a vest or waist coat 馃, also I edited one of the brushes in clip studio to resemble more an actual pencil, I think does look quite similar.
