After drawing a poison bottle I wanted to create an unconventional witch: young instead of old, red instead of violet, pharmacist instead of... well... By the way, I believe that most witches were pharmacists of their time.
So this was merely a color practice with different brushes. I used marker, airbrush and paint. The hair is paint, the face, shirt, bow tie and shading was all used with marker. The airbrush was for the shiny effect on his bow tie. I have no rhyme or reason for this image, it was just something I created in my sketch book. I just needed to draw something to play around with.
