It was a good story idea and a fun song but you didn't use it to it's full potential. Work on the script for a bit, maybe add more characters and an actual plot for extreme comedy while using the entire song and possibly others throughout. I think if you do this and work on the animation, a follow up would be awesome.
You did a good job though, a little short for my taste but greatness starts small.
Upon the very first frame I admit that it wasn't appealing as I think the animation is a bit weak, but when you actually watch it to the point of the first 'scat' it picks up. I think you could have ended this in two different ways- 1) it ends after the first scat and you have that shock 'wtf' moment from viewers and 2) the three dancers end on a group pose and you could show reactions from other party goers (possibly laughing or something).
Regardless it was a good attempt and apart from my own thoughts about the animation, I have no negative opinions. Your voice recordings were very clear, that is always a plus for me.
I think the animation and drawing could be improved but the sound and story worked well and held it together.
Look forward to seeing more in future.
i like it and i think you should keep working on your animations other than that good job
magical, best thing in weeks
