This is a pic of my OC Miles on his personal "Cyclone": a type of hybrid of a fighter and a flying motorcycle. It's power comes from a small steam-powered generator which provides electrical power. It's propelled by to two small, yet powerful propellers on either wing. The propellers and cowlings can rotate to provide either horizontal thrust (standard flight), or vertical thrust (hovering). It shares the same basic principle as the real-life aircraft known as the "Osprey"(except the wing doesn't rotate along with the props). It's also armed with two steam-powered "Xiphos" cannons in front and 6 machine guns in the wings (two barrels are shrouded by the steam.)
This pic was my first attempt at portraying something mechanical. The pic was rushed, and that may consequently show in it a little. But I had no choice but to rush, since this was due for a contest on DA within a day of it's completion.
Materials used: 0.5 mechanical pencil
Approximate Time: At least 3 hours?
