Thanks @steevc! Interestingly enough there was less sketching of ideas than normal. Since it was five pieces all in a bit of a montage style I did rough sketch each individual element, but then I simply started putting them together like collages! I cut & pasted, resized etc. until I had pleasing compositions but pretty much every initial element I had drawn found its way into one of the pieces with very little redrawing, just extra detailing. That’s a big benefit of the digital work vs. doing multiple compositional sketches for each illustration!
