making keychains seems like a really good way to pass the time. I personally make perlers (kandi) and paper dolls, as well as experiment with crafts in order to busy myself. ive been thinking about learning how to sew or do something cool like that, though when i get a job (j-j-job??😱) and a paycheck ill probably buy custom keychains or make them like you.
These are actually so kewt 🐌🐌🌹you shouldn't necessarily make the lineart thicker, but definitely should refine the lineart since you can still see the chicken scratches. Id say only make the outer of the art thicker if that makes sense ;P
