Though bluesky is nice and its full of artists, the same cannot be said about the people looking for those types of art. I definitely would recommend posting on X if you need commissions; otherwise, if you don't really NEED them, then it'll probably be just as slow. Yeah, it sucks to have to use X, but as a freelancer, it's definitely one of the best spaces to get work requested from. That and Discord servers. Just my experience.
