If you have the patience to sit through 7 minutes of someone drawing then watching this recording of me inking a missile mouse panel should be no problem for you. Around 1:16 I make a line that I don't like and pause to decide whether I should fix it or not. I decide to go ahead and fix it. I use correction tape for my mistakes because it's quick and clean. I'm drawing with #2 and #5 Pigma Micron pens.
