Experience in doing animation with Photoshop:
The animating itself was not as difficult as I originally thought. As soon as I understood the concept of frames and layers, I could easily animate given pictures. What I figured harder to do was the actual creating of the different sketches. Since they all have to be very similar and the missing of some, might make your animation look less smooth, I had to a lot of correcting afterwards. To compare the two different projects, the flower and the car, it has to be said that the flower took at least four times as long as the car. While creating the moving car, I was able to use the same sketch for every frame. The flower took longer, since I had to draw all the 42 frames in a different way.
