I also used a mask and some dark blue paint to give me the honeycomb effect, and then for some reason drew a white line across the page with a Posca paint pen. It must have made sense at the time, but I can't for the life of me remember why!
There's something almost biological about the structures I've drawn - arterial branches and cells perhaps - an organic element anyway. It may have been deliberate .... not sure now.
Gosh, I am in reflective mode today! Its probably because tomorrow we fly up and away - visiting Virginia in the USA. Fear not, I have packed a small travel journal with prepared background pages, plus some new drawing materials and a notebook ... just in case the spirit moves me to work in one of them. What's the betting I'll be so busy eating ice-cream and gazing at the views that I forget to do any of it?
See you in a couple of weeks or so.
