One tip: any good animation, starts with a good story. If you wish to be good at this, you'll need to start by working on that.
I'm not going to judge you on your animation quality, cause this is your first and I'm sure you'll improve. But you'll find out that having a good story can get you far, even with a not so good animation.
I'm giving you 1 star, but it's not to say give up, it's to say: TRY AGAIN, keep going, get better
And be sure to catch the audience's attention
