Animating And Colour Choices

After settling on the design I was going to use for my animation, I drew the sheet below to sum up which parts of rocket were going to be animated and what colour the different components were going to be.
The first thing I chose to be animated were the wheels. As the wheels have four perfect lines of symmetry, it is possible to create a short loop of two frames. The first frame will show the wheel in its stationary position, in the second frame the wheel will be rotated about 45 degrees. This loop will give the impression that the wheels are moving. The second component I wish to animate is the fire. I have chosen to give this a loop of three frames. I do not want the fire to have a smooth movement like the wheels, instead I have chosen to draw the fire a slightly different size for each frame. This loop will give the fire some "life". The last loop I am creating will be for the eyes. This will be the longest loop and it will be four frames long. The first frame will show the eyes being open, the second and third will show them shut, and the fourth frame will show them open again to complete the loop.

I have thought hard about the colour selection for the rocket and I have come to a conclusion. The main body of the rocket will be white. I chose white because it will save time when drawing each frame of the animation. As I drew the wheels to look like old fashioned cart wheels, I have chosen the colour brown to mimic the colour of wood. The pupils of the eyes will be black and the irises will be yellow. I chose yellow because it is a vibrant and bright colour that will catch the audience's attention. The tip (or nose) of the rocket will be red. After watching some cartoons and feature length animations such as Toy Story I found that the nose colour for rockets is primarily red, this is my reason for choosing this colour. For the fire I have settled on three colours: Red for the outer flame, pink for the middle and yellow for the inner flame.
