Not as good as the first one
The first submission you had here was really great, but this was not so much. Do not get me wrong, I thought the animation was nice and everything. It just seems like you could have put more effort into making something like this. It does work really well as a short cycle but that's not the sort of thing we expect on this website. At least you have good animation and were nice enough to use that classic music. I never played "Yoshi's Island" as a kid (or an adult) but I recognize this music.
I think the thing you really want to look for is if there are things popping up in the background. While not the most creative, there a couple of those things that show up. The best example of detail is probably the blue mountains. Many things here have a lot of designs even if it does not come off as elaborate. I believe you said, "Link in comments", but I don't see a link in the author comments.
