mostly likely there are more than two even. there might be a whole team working on the drawing, so every panel might be a little different.
Well whole team is common. But generally each of the members have one specific role. Like- drafting, coloring, bg, effects, toning, shading, lighting or just lining.
But i feel like atleast two artists are sharing the same role, which is making the differences. It feels kinda unsetteling to see the changes, as im used to the consistence drawing pattern.
It could also be a time issue, if they're in a rush some panels might look a bit messy
Are there two artists for the character drawings? Some panels have this amature style for border lining. Only e few panels have smooth and more refined strokes.
