Needs sound effects. This was a skilled practice at frame-by-frame animation and onion skins are clearly your friend. That's great! With a little more practice, it can look a little less wobbly. The framing and composition is inconsistent. Sometimes the cloud character is hugging the edge of the screen, and it's just framed kinda weird. I suggest looking into "The rule of thirds" and try to keep that in mind as you focus the camera on what you mean to be focusing on.

Great start! Keep at it!
