So... I just found out that you stated the following on your ref sheet pages:
"Finally got around to revamping the trait sheets! Keep in mind that all traits shown above are the base. Some traits will differ in look, sometimes more drastically than others. Feel free to bend shapes and features to stylize any trait to your liking. Read up more on the species here: https://www.furaffinity.net/view/43685587/ Zorgoias are an OPEN SPECIES! Feel free to make them, sell them, do whatever you want with them! No permission is needed, but please do not claim that you made Zorgoias and I would love to see what you create."
Quoted from your own ref sheet pages on furaffinity stating that the source is from the free ref sheet, hereby voiding your DMCA and I have right to persue legal action if you bring this up again as you ALSO never gave me no notice prior to filing the DMCA against me.
Consider this your final notice!
Also, DMCA-ing, and editing / modifying something after prior permission has already been granted that is a Creative Commons / Open License, means the DMCA is a Material Misrepresentation (Bad Faith Takedown).
