> That's a pro tip, right there. All too often I get caught up in using the tool/program I'm in to do something completely, where it causes inefficient work loops. I was caught in that loop with the first couple of chapters where I felt like the drawing itself had to be perfect and I would redraw them if I made a mistake. I got wrapped up in some sort of purist ideal (an affliction I am highly susceptible to). Eventually I realized that all that matters is the final image, so I got better about taking advantage of Photoshop. Each line and letter in the diagram was still drawn by hand on paper, but sometimes I rearrange or fix mistakes in Photoshop.
