After checking out some tutorials online I decided to try a different method of drawing using silhouettes as a few concept designers do this and i had never tried it.
For the first step I took a light Derwent charcoal pencil and scribbled down some rough shapes it took less than a minute for each one, then I took a putty eraser and cleaned up the shapes.
I used the charcoal pencil to define shapes I liked.
Then I took a Faber-Castell 8B pencil and added some detail.
