I have been a member of FurAffinity for over ten years. It is a decent place to be in terms of long time discoverability because of how well everyone knows the name FurAffinity regardless if you are a furry or not, however that is also a conundrum in itself.
Unless you are a successful "popĆ¼fur", which is a nickname for being a popular furry, or have a higher audience on some other website to self-promote and advertise your profile, then good luck getting noticed. Because unless if you make fursuits or flooding tons of explicit nsfw works into your gallery for a more perverse audience, nobody really cares who you are on FurAffinity if you don't meet anyone's extremely high and biased expectations.
No matter how hard you try to improve your art, your view count is low, people rarely comment and favourites are also low. You'd be better off sticking to DeviantArt, they offer a groups function that allows you to get your art pushed out into other people's inboxes, regardless if they follow you personally or not, for those watching art groups and you'd have a better chance of exposure on there unlike FurAffinity's way of having a temporary display on the front page before it gets lost in the art portal where it'll be forgotten.
The website is also frequently known for being targeted under multiple DDoS attacks causing it to shut down temporarily, so if that also isn't a warning sign about how unorganized and outdated this website is then I don't know what is. There was also a rumor they once hired a hacker as one of their admins years ago which also left some damage on the reputation of the types of people they hire on their staff team.
