OK. I don't know how you do it, or how you get from sketches to final art, but this is the way I do it. More refinement of individual images, and drawing the characters in ink and building the image from a bunch of different drawings. After I draw things umpteen times, I select the winners for consistency of line and "quality" and then on to scanning, cleanup, stitching the pieces together and then digitally coloring. The color is in the back of my mind throughout the process, I have a rough idea of what I want to do. This is the part that I find most tedious.Sure, it would probably be easier to do it all digitally, but like I said, this is the way I do it, especially on a complicated piece like this with so many moving parts. I find comfort in overthinking and reworking things.
