>>390402It 'works' for humuhumu because she literally has done professional work for high-profile companies, and attempts to actually teach people of all skill levels how to have a basic level of drawing by doing excercises with her viewers mid stream. Iofi was just a weeb that was at an average level of drawing when she first joined whilst claiming herself to be the 'artist holo', which made her look silly next to someone like Flare or Marine, who were excellent at being entertaining in other areas alongside being amazing artists. Though she has gotten better, Iofi doesn't attempt to teach her viewers how to draw or do anything fun with it, and she still doesn't really have anything going for her other than her frequently collabing with Holostars.
Iofi is suffering from the same issues Holos like Roboco, Mel and Choco are, which is Holos already filling roles, or having their roles taken by other holos. They no longer have a niche to fill, and so they recieve less traffic because of it. This was naturally bound to happen as more generations were created and the new blood cannibalize their senpai's audience.
