Great News! I've recently updated my Carrd, now it includes a Portfolio and a section for my Commission Info.
Figured making a portfolio/ archive of my work, making it easier to have a central spot for people who visit my carrd to see my work (without needing an account for anything.) You might find art you've never seen before!
Same thing with my commissions, I've added a tab to see my Prices, ToS, Queue, and my Forms! (yes you'd have to fill out a form, I'm trying to be professional about this!)
Please check it out!
