Hey! The animation is really good and the character designs are rather distinct! I have no idea if you crafted this yourself or "traced" the actions from an existing video; however, if you make more videos with this kind of fluidity, then you are going places!
EDIT: Thanks for telling me that you didn't trace! I will point out that using animation as reference is nothing to be ashamed of. As long as you don't directly trace and maybe add your own spin to the action, then it's perfectly fine! Keep up the great work!
