In my experience with the sketching workshops, I've noticed that many design students have problems rendering complicated products that are made out of several different materials. In this tutorial, our product is a handheld vacuum cleaner. It’s a good product for seeing the difference between plastic types, such as matte, glossy, and transparent. For the transparent surfaces, the Copic Airbrush system is really effective.

As usual, I lay down the first layers with light gray tones N1 and N2. Before using the airbrush, I try to do the detailing inside the transparent surface. 

Before starting the airbrushing process, I create a mask with another paper on top of the drawing.

I start with a light layer of R05 with the airbrush.

Then I add another mask and do a heavier layer of airbrushing.

The sketch without the masking.

After the airbrushing process, I render the gray parts of the vacuum cleaner with N3.

I use the neutral grays and blacks to render the dark matte plastic surface on the handle. 

I use a set square to create a straight line for the background.

Copic WIDEs are perfect for creating backgrounds. I really like the big marker effect behind the design sketch.

Here is the final sketch!
