Paint materials with a sense of history
First I create my two- point perspective grid to support my drawing, and quickly block in the silhouette of my ship based on a rough sketch. I imagine that this is a fast cargo ship, designed for carrying goods around the planet, so I lay down a simple, aerodynamic shape. After changing the shape of my ship I add details. I try to find a balance between larger shapes and smaller, more complex elements. You can enhance the realism of your piece by breaking up the bigger surfaces with small details, such as the lines of the panelling, and mediumsized shapes like the paint scheme. Now I add the ageing and weathering to all the materials on display. I always try to create a little story in my head and imagine what the ship has been gone through. Try to vary the ageing by using different distressing techniques on the materials, such as rust, dust, dirt, scratches, dents and peeling paint.
