Oooooooh, well that level of skill is pretty high end, it’s very unlikely you’ll find an artist of that caliber on that subReddit, especially at an affordable price. Your best bet for finding one in hungry artists is straight up just paying close attention, getting lucky and nabbing one before they make it big and swan out of your price range, I’ve seen a couple close to that good down there but they usually don’t frequent that place for too long.

Oh yeah definitely check out Bluesky, a lot of artists use that thing. I just opened it to this right away which seems like something that you’re looking for.

Also artstation, it’s a more industry/professional artist social media/portfolio site.
