A steel hovercraft carrying supplies

 And this time, the picked subject was a steel hovercraft carrying supplies. Quite the challenge for me, because I don't draw machines and other technological things. So this was a challenging challenge.

Of course the first thing to do is sketching. I started out with some writings first to get an idea. Then the small sketches were drawn.

I decided on an one-person hovercraft with supplies. It's easy, it won't get a lot of attention and it can be very fast. 

After the sketch, a clean lineart was created. This took quite some time, so the only shading added it the shading on the propeller, the glass and the "balloon-kinda-thingies".
