great art
I think what other people were calling 'slow' was the progression from one step to another. like, the character able to materialize giant pencils and kites would think fast enough to make what they do in the movie go faster. We already suspended disbelief of the norm once, having to do so again makes watching a movie feel a little clumsy.
Fill out the character a little more; answer questions we haven't asked yet. Your drawing style is pretty solid already, practice writing a well-received script :)
