My not so great thaumatrope!!!

So as a pretty creative person I thought that when I got given the task to create my own thaumatrope I would do a pretty good job.... Oh how wrong I was. I decided that I wouldn't follow any instructions and try and do it myself, what a bad idea. Even though I was extremely proud of my drawings not happy that I buggered it completely but I still did step by step pictures of my own.

What went wrong?
I think the things that went wrong were my circle was too big, the wholes that I made in the side weren't in the centre and my pictures on both sides weren't level.
