I drew this in a Moleskine while waiting to be picked at jury duty. I used a Pentel mechanical pencil and Faber-Castell Pitt Pens. This piece is totally off the dome, so it’s not based on any real ship or wreck, and the name “Halifax” is probably already used somewhere else, but I am happy with how it turned out.
I heard Jim Lee (THE top comic artist of the last 20 years) speak long ago about non-photocopy blue pencils. You sketch in pencil, then pick out the best lines in non-photo blue and erase, only the blue lines will remain, allowing you to have a nice wire frame for your drawing that can easily be removed upon scanning. These days, you can even do it with a mechanical pencil: Like this Pentel Sharp 205 with 0.5mm non-photo blue lead.
