Medium of my Stop Motion Animation :o

For my stop motion animation, I was thinking that for medium I will chose plasticine and paper OR only draw it. I selected this two because there are the simplest way to do my specific stop motion animation.

If I choose drawing, I will have to draw it and then erase it and make changes but I think this is going to take too much time or I am going to end up very tired of drawing it. If I do it with plasticine and paper. I will draw the objects in plasticine and the background in paper and will make changes every picture. But the problem here is that if I do it with Plasticine, some colors from it will blend I it wouldn't look so pretty
