I have changed up a lot of things on the Patreon page in regards to the Tiers. If you are a patron of mine, you have likely been removed from your tier, please go reclaim your spot. I had to do that, since I changed a lot and didn't want people thinking they had a tier reward that's now different.
There is more info in that post, but here is the quick list:
Headshots has moved to $20 and a new 30-minute artwork tier is at $10.
Fullbodies is at $35 now instead of $30.
Added a new $70 design-a-character tier.
Removed all ability to use text-only references outside of the design tier.
