Rendering white is a tricky endeavor but once I understood that white is really about varying shades of grey and even black, I dove into testing different tools. Below, you can see an example of a photo I found in a fashion magazine. I sketched the overall shape and then made copies of the outline to use different media to finish the illustration.
For the middle image, I used color pencils and crayons. I touched up certain areas with a black ink pen to give the illustration a dimension. The image on the right is done in markers only. I think the two illustrations do have a slightly different feel to them and I am excited to keep testing ideas!
Do you have a skill you wish to hone in on? What is your strategy?
