>artist goes to patreon
>barely ever see his art anymore since he doesn't do enough free stuff to get promoted on twitter anymore
>randomly remember him after a few years
>go check it out
>anatomy went to shit, sameface and same positions over and over again, shading and lighting didn't improve, produces less than half of what used to produce
Why is this so common? Does Patreon has a curse that makes every artist plateau and then degrade? What the fuck is even this?
