I really like the design of Alfie and the old school CGI feeling of the work...There's been a trend for awhile of people searching for "lost footage" of 3d animations from the early 2000's like Shrek (there's forums dedicated to it, I believe) and I'm personally playing around with A:M because I want to create stuff with the retro feel of films like "The Mind's Eye" and ReBoot.
As for commercialization, I know there was a period several years back where posting kids animation on Youtube was a seemingly easy way for some money but it was being flooded with content that was inappropriate and so Youtube updated their policies and requirements for being able to monetize. I think they made it so that videos have to be a certain length of time and meet policy requirements and I've no idea if they've limited the use of AI for monetization.
That being said, I have a Roku TV and was flipping through their free channels during Christmas last year and there was an animated Christmas movie playing that was legitimately just clips of animated characters dancing looped, motion-tracked dances. If you cut to the 35 minute mark you can watch a dancing ginger bread man...I highly doubt the people involved did it for free, someone must have been paid, and I've had a look and Roku does pay for content: https://developer.roku.com/en-ca/trc-docs/video-on-demand/ad-supported/getting-started.md Not sure what the money is like though, but could definitely look at submitting Bella Bear for Roku channels.
