pretty good. try some backgrounds, they really make it a lot better.
about the collab: did u remove it? anyway it wouldve been WAAAAAAAAAY too involved, and not really that great since it'd be 10 different people animating the exact same story, and spending 3 months working on it. if your gonna do a collab, do something much more realistic and general (like fight, bawlz collab, guns collab, etc.)
