I really like how Kon and Ri's ofuda we got shown on Twitter are sort of glimpses into their characters.
Konโs is more neat and meticulous, like there was care put into it. Every line is smooth. All the eyes are facing forward which makes it feel more confident in a way, but they're also not quite as open as Ri's.
Meanwhile, Ri's looks more messy and hastily made, no care about making it look good. There's edges and uneven lines. The eyes are all wide open and looking in all directions, as if making sure they won't miss anything.
Also, not to mention Kon's looks more modern than Ri's which is interesting. Idk I just noticed and thought this was cool.
Edit: Another thing I found under the cut โคต๏ธโคต๏ธ
