I think all the animators did a great job and this review has nothing to do with them,
however I do think the way the organizer cut/separated the scenes is really janky. Some of scenes are way too short and should probably not have been cut in the way they have in this collab. This is mostly in the intro and ending scenes (for example 7 seconds in; there is a scene of Mario that's not even a second long)
Because of how much you split some of these scenes, this collab just doesn't mesh well together and in the end its really awkward, especially in the end.
The collab organizer also somehow managed to credit me with the WRONG name despite the fact I mentioned my username TWICE in the emails. IDK fam, sorry for being so harsh, but as someone who volunteered to manage a collab with more than 200 animators; I really don't know how you went wrong there. :(
