I have finally uploaded all (or at least for the sites that don't have daily upload limits) the commissions I've been sitting on for... years in some cases.

I like to have two copies of art when I commission an artist: A high-rez print-ready PNG (or other lossless file format), and a lower-rez JPEG (or PNG); this is so I have a copy just for myself to print for my home collection (lately I've been sticking SFW prints to the walls of my computer room while NSFW prints go into a nice portfolio to show friends of the furry persuasion), and a copy that I can share around with a link to the artist's pages (which in some cases have the high-rez file if they are okay with others having print-ready files of their work). I don't want attention for picking a popular artist to depict my characters, they deserve all the credit for the work they've done, and my own artistic journey has revealed just how labor intense even a simple colouring job can be [when done right], let alone making a whole piece of art from scratch! Really all I want is to A) have all my character stuff displayed for others to enjoy and B) shout from the mountain top, "Hey! This really cool person made really cool art of my characters that I think is really cool; here's a little demo of what they made, now go give them your time/money/eyeballs!"

Right now I operate on the honor system: If it's made by me it will be uploaded as a high-quality PNG, and if it's by someone else it will be basically a preview with a link to the original artist; if I find out that my PNGs are being printed and sold for personal profit/attention without permission, y'all will be getting coal (crunchy jpegs with the most obnoxious watermarks) for the rest of the time I decide to share my artwork online.
