This one was extremely fun. I wrote this comic book, hired an artist to do black & white line art, and then colored it myself. The black and white art that I received is on the left, and my final colored image is on the right. It took roughly 6 hours per page to color. These are pages 5, 6, and 25 of G.F.O.R.C.E. #1, available in print on gravitycomics.net or digitally from comiXology.
