Is it really such a bad job that a hard rejection?
This is my idea.
Just don’t expect your project to be accepted with the photos getting smaller and bigger. see what scenes have already been made.
This is just too simple and kinda clunky.
My suggestion would be read more design resources, learn about composing a scene, and seee lots and lots of references of top projects. See the pace of the animations, the smoothness, with time you will start to get it more and more.
