All the artwork has been created in Procreate. For the past 2 months I have been drawing hair, outfits, accessories, and more. This is a bit of a tedious task, but when I import all the layers into the random NFT generator it's well worth the work.
First I do a rough sketch over the base model. Second I outline the sketch to clean up the line art. Third I color the hair and outfit. Finally I export the hair and the outfit as two separate transparent PNGs.
