Fun fact number 8 million: The pages that were just Specter and Spike were the quickest to draw due to a combination of having drawn them the most over the last year and a half alongside, and also because I've drawn them so much that I could scroll through all my doodles and drawings and flip head assets during the pencils phase so I didn't have to redraw from scratch if I already had a good head in that pose. Almost every single head of Specter was facing the wrong way that I needed so I still had to redraw in the opposite side of his face and switch his bangs on almost EVERY shot of his I reused.

The moral of the story is this: If you want to draw a comic draw the characters a lot. Start and ask blog even and let your friends ask questions that you answer with quick sketches and other doodles, because not only does that teach how to draw the character from scratch but ALSO every good asset you make you can reuse to make pages quicker.
(Because in reality nobody cares if you drew it all from scratch of if you inked with a pen or had the amazing hand eye coordination to ink with a brush, as long as the end result is readable.)
