Content visuals and animation

I have been trying a few attempts on the art style and animation for the content "falling". Because I can't make the feeling I wanted.

The character looks weird and I can't seem to point it out where. Maybe is the clouds or the background is too empty. So I did more research and finding on which I came across the animation shown below. The animation is just how I imagine being so I take it as my reference.

I will be taking the outline and animation as my reference on the first gif and the character on the second gif with some parts moving like the hand and feet. There is a missing progress where I did not change the character's back and the feedback I get from my specialist is the character looks wired because of its hands are too long and another is too small. The back of the character looks bumpy and heavy, whereas my reference looks lightweight.   

In the end, I change the hands and added texture to the body parts. Also, lines in the background along with the back of the character smoothen. There is still more improvement to make, like the character can be floating up and down, the could can changes to something more finalize. I kind of think of wanted to remove the line animation because I would have the background like (building, mountain, cliff and normal sky).

Thoughts of the day:
When I start animating the visuals, I start to think of how would my visuals and UI added together would be? I feel like I am not satisfied with the outcome and I wish to improve. I want to design something minimalist like what my target user would want to see, and I hope I could do my best to improve anything possible.
