May I ask you a suggestion on how to make such cool and smooth outline strokes? It's not a nomal shape stroke for sure. Maybe additional stroke paths that you manipulate like the rest of the shapes?
Sorry for bothering, I just want to improve and yours are one of the coolest stickers I've seen in this contest :)
