Honestly I just don't think there are too many users here who are actively looking for artists to commission. We are a small community, and many of us here are artists ourselves, and don't have much of a need for paid services from another artist. We see more collaborations and trades and such around here. When I do see artists posting commissions they've completed, I notice it is usually a piece they did for a client on Twitter or other social media.
I would suggest searching for commissioners in the furry fandom instead, where artists are in higher demand. Even then it is not easy. Most of the successful freelance artists I have seen are those who have built up a dedicated following of fans, who expect a specific type of content from them. You might have more luck specializing than as a generalist. But I only recommend doing that if you have a specific interest that you are passionate enough about, that you would enjoy catering to it specifically.
Also as a furry artist, it would be beneficial to have Telegram as a second means of contact along with Discord. It is the most popular messaging app for furries, and you can also create your own channel, to post your art and advertise commissions to your followers directly.
I've heard streaming your drawing process on Picarto is a good way to engage with your audience, too. A lot of commissioners like the personal interaction of being able to communicate with their artist in real time as they work. I don't think I could handle that myself personally though, it seems it would be stressful to be under that kind of scrutiny.
