Dear Bonbibonkers,
Take your clothes off or wear skimpier clothes. Something that you haven't worn as a regular cosplay before.
Clean your room or get a backdrop
Pose like you're a pin-up model, not like you're taking drunk selfies
Use a better camera, or at very least don't cover your face with your phone
Make something that is worth the $100 in effort and quality or else no one (besides paypigs) will buy it.
