I drew this study while sitting on the beach with only a Sharpie thin inking pen. It is meant to demonstrate how I captured the motion of the waves as they were moving and my thought processes involved. The key is to show motion where there is none. This effect can be achieved by letting your hand flow freely across your paper preventing rigid none fluid lines from taking over. Nicely placed contour lines give the waves depth and a feel that they are full and really on your paper…not just a one-dimensional entity.
The clouds can have weight and depth too. Simply applying horizontal lines…more for a denser cloud, and fewer for lighter clouds. This technique gives your clouds the appearance of being full and being able to cast a shadow below. Circular shapes in the clouds give them that airy look as the wind slowly carries them away.
Helpful? Hope so. There is no right or wrong way to create these affects. Experiment over and over again and you will find that your drawings will improve and appear to be more life like.
