Stage 16

Since it is hard to tell exactly what the drawing is going to look like when you remove the masking you may find that you need to repeat the masking and spraying stage a couple of times. Here I have decided that my wheel arches are a little too dark and not prominent enough. I have therefore done another quick mask and lightened them up with a touch of yellow.

Stage 17

When you feel that you have completed all your marker and airbrush it is time to move onto the final stage. Bringing out some shut lines and highlights. On this drawing I felt I wanted to keep this to a minimum to avoid cluttering an already very complex shape. The idea is however that a shut line compromises two coloured lines. A dark line on the edge facing away from the light source, and a lighter line on the edge facing towards the light source. Try and avoid using black and white for these lines, and instead try to use lighter or darker tones of the colour in which you have used on the body panels the line cuts through.

Stage 18

In order to add highlights to the vehicle I have began by drawing a very faint white line through the body. Onto this line will fall the brightest highlights. The further you move from this line the less intense the highlights will be. Try and place the line so that it does not pass through areas that will be awkward to highlight. Having drawn this line I have then used a white airbrush to really punch out the areas that are reflecting the light. If you are using a real airbrush as opposed to working on Photoshop this is the stage in which you should really take care, as mistakes will be very, very hard to remedy.
