Much of my work in advertising involves healthcare...ranging from finished art (watercolors) to comps and storyboards.
I use pencil, pen and ink, watercolor, Photoshop to bring about a variety of techniques.
The ability to draw people of different ages, including older people and babies is a definate plus for me. I continue to stretch myself to come up with more techniques and to expand my abilities.
My most recent brochure was for Bristol-Meyers Squibb using watercolor to depict tumor biology to advance cancer therapy.
