This was drawn with a 8b Faber Castell pencil.

These are quality pencils, which remain smooth `til the last stroke. No scratching the page at all with these.
 For the shading, I used the Lyra Graphite Stick, because this will cover a wider area much quicker.

I find the Graphite has a less dense tonal range than the charcoal, but then, sometimes, that`s what you need.
