This is the last of the box frame pencil drawings that I'll be doing for now.
This one was especially difficult to do as I had to fly to Hanoi and hire a helicopter in order to draw it. It's really hard to draw in a helicopter as the propellor makes so much noise that it's difficult to concentrate. In the end I climbed out of the 'copter and down a little rope ladder like you see in the movies in order to escape the noise. That was much easier.
