Pencil base layer on white paper stock photographed then imported to iPad for all else. I like oil crayon, thick and wiped nibbing and watercolour. Sketch has the better pen and charcoal base layer tools but I prefer Procreate for better blending and colours, I bought the extra Sketch nibs as an add-in purchase, well worth it and Procreate for the watercolour mixing. I then go back into Sketch for a spray and lighting and a little bit of Adobe Draw for different lighting glow effects. I use Adobe Photoshop Mix to drop the barcode then back. I was low energy when I responded. I don't really get to talk about my process except among furry artists on twitter where we all share techniques.
I'll repost it and can point out the areas where the different apps are used or you could pop into our video stream sometime, I am mostly using picarto rather than twitch. We are a friendly lot.
The box to the right is an error its the clipping retainer for the barcode I shoved off screen, but its now a feature!
