It's a start...
Certainly you are giving your first steps here and I praise you for that, but there are somethings that you need to put attention to:
- Yes, there are drawing styles that are made to llok messy: but this doesn't feel like that, I recommend you to watch some other animations on styles you find similar to ours, put attention to the details on them since they'll lead you to know how they did them.
- Define your character better: Make some standing still art from different angles until you are confident that you know your character as well as you know some real-life person
- Animate by parts: it seemed to me that you made the whole thing on a run rather than animating the bunny first, then the main character, then the backgrounds. that way you'll put more attention to the details of each part.
- Define your line-art: Some of the traces (like one of an eye blinking) seemed to be done on a rush and carelessly, don't animate on a hurry, take your time, defined lineart and colouring make most of the animations good or bad.
- Have fun: and don't give a damn about aggressie or rude comments, check who says them most will come from people that don't create anything and have no idea of the work behind your art, real artists will guide you rather than mock you (...but not forever so make an effort to improve with their comments).
If I'm being this hard is because I saw ambition on your animation, work hard for it!
