LOOK AWAY CHILDREN--
My first preset was Nyan Cat, made in MS Paint. It looks pretty awful XD Oh well, I guess we have to learn somewhere.
Sadly I do not recall my first preset, but I do know that it most likely wasn't all that pretty. xD
Though I unfortunately have no screenshots, I remember my first preset being an unholy orange and white stripy mess. Kinda looked like a melted creamsicle. My retired OC Nevica had some unfortunate design changes, since last-year me had some stranggge tastes.
