Help me improve this chest obtaining animation!

I created an animation that will play when the player collects a chest in my game. Even though in the video it isn’t shown, it is supposed to be used at a few reward checkpoints that the player is supposed to reach to get these chests (and currency as well).

I’m looking to see if I can improve this animation in some way. My animation is heavily inspired by this one (If the video isnt on 4:13, just go there) :

Please tell me if there is anything to improve in my animation.
