The reason why Dinety has a darker step mask instead of 40's color is because a brighter step mask wouldnt go well with his dark design, and 15 and 21 have a dark step mask so i did the same. Also the eyebrows look like that as 180 is related to angles but 36 is not, and 36 is the smallest number that is both a square and a triangular numbers (The next one is over 1000) so i changed the eyebrows to a square and a triangle.
