This process was an emotional roller coaster for me. I think the most difficult part for me was definitely the pen drawings. I was finding that that with pencil it was far easier to vary the intensity of the line weight. Additionally the wider expanses of similar toned (light gray) areas I struggled with making a consistent tone. I think my biggest worry was not leaving enough space for the highlights and lighter areas in my pen drawings, as I was afraid that they would darker too quickly.
My suggestions here are the same as I mentioned in my email. In the process you could tighten up the resolution by hatching lightly from many angles rather than just two, as suggested in the demo.
The hatching in the pen drawings is fine, but as before, these need to be several shades darker overall.
