The image in the last step looks a bit strange with those tiny and thin outlines... That's what we are going to change now.
This time I added dynamics to the outlines with the Copic multiliners black and sepia (both size 0.05); and I did fill in the parts which were supposed to be black e.g. the eyes. For this I had to trace every single line again. It's quiet a lengthy process but it's worth it!
