I have been searching for more storyboard examples to post but have not had any luck. I found some ink line drawings that I did for my book DRAWING IN INK. These images illustrate the variations possible when using this medium, you can do a straight line drawing and can add blacks or gray tones to make them more detailed.
All three versions of each subject work quite well. Actually I could have even done a few more variations. when doing line art it can be fun to experiment with some of the possibilities. You can also try adding washes of gray or color tones. Another fun experiment would be to scan the art into the computer and then add gray or color tones.tones
