I'm new to Patreon but I post all my fan art there regularly and there is a crap load of FFXV. My reward tiers are nude/NSFW doodles for $2, a middle tier which can include a variety of things (check description) at $5, and my biggest tier for fully-colored & linearted NSFW drawings at $10. I may add more in the future.

I'm not up to date with this hellsite anymore so I'll just dump my shit on occasion, lmao.
