Like every detailed drawing I do, I first divide the page up into little square grids. I then work out the perspective and block in the main shapes. After this I head straight into the detail with a light 4h or 2h pencil.
The drawing above has all the main details that I need. It's only drawn with a 2H pencil, and I'll go over it firstly with a HB pencil, and then a 4B pencil. This is to define the details and make the value lighter and darker. You can see how it goes in the next few pics.
I hope ye like this drawing and found this post helpful. If you have any idea's on interesting places for me to draw, let me know. :)
