This Sakura Cardcaptor's fanart is part of a collection called Magical Girls With Armors.
Magical Girls With Armors consists in a collection of 5 prints, each one with their respective sticker. It is supposed to be printed in risography, with a fluor pink ink, and black ink. The designs are characters from classic magical girl animes, but redesigning their clothes and some weapons to do it more like a medieval/armor look like. The style used is a cartoon but detailed textures for some of the pieces.
