omfg, I thought I had nothing to add but there is something I;ve been wanting for a while.

The ability to buy portfolio's, sort of like bandcamp? pay a small or flat fee for hi-res images (or groups of) without monthly support. So I could put up all my art as one portfolio, someone comes along to my "patreon" and can back my work monthly to see constant updates, WIPS etc etc, or can just check out what portfolio's I have up. If they only like my finished work they could outright buy a portfolio of digital files for a once off flat fee. Could have the ability for multiple folio's for people that want to split it into categories, or single images etc.
