I am using Sketchbook Pro to redraw the line art on some older illustrations that I no longer have or have access to.
I do have them on slides which are worn and faded and I'm using PaintShop Pro to clean them up first.
When I was teenager I saw this advertisement in a magazine of a pterodactyl with absurdly huge landing gear as feet. It was so cool I copied it on the spot. later I stared drawing my own take on it with smaller landing gear a saddle and a rider or two. I've been drawing versions of it ever since.
