Are my sketches messy?

Wel...

The other day I was watching rise of the guardians and I realised that if the guardians get weaker if children don't believe in them, like when the tooth fairy couldn't fly, then jack must be so fucking powerful, like if he can do the things he's doing the entire film without a single child believing in him, then when children start believing in him he would be much stronger and powerful

Can someone explain me why I had paused ladybug and this is what I saw?

I simply love it.
