Jack Sparrow step by step

A small tutorial (see some explanations at the bottom of this description) for my latest traditional mixed media drawing "Jack Sparrow (drawing)".
I photographed the steps 1-11 with my Canon EOS 600D (EOS Rebel T3i) without flash. I'm sorry for the bad quality, but the light conditions were suboptimal. Step 12 is the scan.

Here are some more detailed step by step tutorials/descriptions + the finished drawing:


These are the different tools I used for every step (and some side notes):

step 1: paper A4 (210x297mm, 190 g/m²), Faber-Castell pencil HB and  set square + ruler + Faber-Castell pencel H3 (for the grid)
step 2: Faber-Castell Perfection 7056 (eraser pencil) to erase the grid lines
step 3: Faber-Castell pencil HB or Faber-Castell grip 1345 HB 0.5 for detailed line art
step 4: eraser, Faber-Castell Perfection 7056 to erase the outlines a bit
step 5: Copic Ciao and Sketch marker for the marker base layer (I would finish the marker base layer for other drawings first, but in this case I continued with the face, because it's easier to mess up a small face than to mess up the marker base layer)
step 6: Faber-Castell Polychromos artists' colour pencils (usually I start with black and sometimes white details when I draw with colored pencils)
step 7: Faber-Castell Polychromos artists' colour pencils, set square
step 8: Copic Ciao and Sketch marker (marker base layer)
step 9: Faber-Castell Polychromos artists' colour pencils (colored pencil layer, details)
step 10: uni-ball Signo pigment ink um-153 white for white highlights
step 11: Faber-Castell Polychromos artists' colour pencils (to define/scratch the white gel pen lines/points)
step 12: edited scan (a.k.a. destruction of contrast and colour)
