Bewyx has been creatively stagnant for years. I'm assuming he releases so many animations each month because that brings in subscribers. If he worked on fewer animations and put more work into each he could be making better content. But beyond that he also could be taking the time to learn new things as an animator. Look at any other animator around his skill level and beyond and you'll see how much they've improved over time. Bewyx is making the same animations he was 3 years ago. I just think it's a little sad because of how much potential he has.
Clearly it's working out for him because he's making good money on Patreon.
