Producing the Bus Scene

I started out with a dark purple background for the image

I then added an interior rear view window and a darker area of purple to show that the shape of the interior bus. I also created a a chair that I mirrored to look like a row of seats.

Duplicated the seats to show two rows of seats

I then made the right hand wall with windows expanding as they come toward you to simulate a sense of depth in the bus. The darker purple is to show the shape of the bus arc.

I then added a double row of seats for the right hand wall in parallel with the centre row and added a black outline to the window as they felt somewhat flat.

I then mirrored the right half onto the left and the bus is finished. Speed lines will be added into the final animation going past the windows to simulate a speedy drive.
