ISO tag background or collab

putting a sketch i just bought off kylo to use through a pixel tag. i've created these line so far along with a few different mane/tail options. shown here are my braided mane and short tail options. i've created cropped mane, long mane, and long tail options as well. i'm either looking for a ready to go 150x150 pixel background to purchase to use in this tag, or someone who would like to collab and create a background specific to my choice and receive profits from any sales.

examples and prices below, please. will close should there be a lack of interest.
