Honestly, very bad.
It had a good concept but the execution was poor.
1. The artwork was terrible, looking rough on everything.
2. You cannot make a full animation in under an hour, that's crazy talk.
3. No audio, why?
4. It feels like a slideshow rather than an animation, that isn't good...
5. Bland backgrounds are poor and uninspired, to the point of being unnoticeable.
Here are some things you can work on to make your next animation better. Since this is your first, I will not bash you in. Good luck...
