Zoetrope evaluation

For a mini-task we had to create a zoetrope. For this I had a decent idea of someone walking across a bridge and at first it seemed to be going really well, I added them on to a template on photoshop. The photos came out really well the problems didn't begin to arise until I had to actually create the zoetrope when putting it together kept going wrong and I wasn't able to create a base for it. After quite a few attempts I eventually had to give up with as it just wasn't going to work. The photos for the zoetrope I am really happy with really only the making of the zoetrope the problem. I feel that if I was able to redo it, it may come out a lot better than before.
