Mentors can influence us in a number of ways including our attitudes towards life, our studio habits and how learn to see the visual world. But it is rare that a Master Artist's style will look like his/her mentor's style. (Look at the difference in style between Mosby and Schmid.) It's the deeper stuff that evolves individual styles and modes of expression--we learn painting skills and concepts, and then develop
them according to what we, ourselves, discover we can make them do.
A real mentor will guide you to express your own voice rather than form you.
