I was also schooled in the fine arts and love to draw in any medium. An illustration is not fine art though, it must communicate a message.
Unfortunately, these days learning to be a graphic designer is more about learning how to use a computer, rather than learning how to create images that communicate a message in a beautiful manner. And many designers just use stock art and don't have the experience of illustrating or working with an illustrator. For more examples of my illustrations see my logos.
