My mentor,master,director at his private art school in the 80's was an extraordinary teacher as well as professional ilustrator,he used his expertise to teach COMMERCIAL ART AND ILLUSTRATION at school.He was without a doubt the best at whatever media he was teaching and always compared his work to the best in the field and was better.His true genius was in teaching at whatever level of talent you were at and that was his his specialty.You sound much like he did and the love of the art shows through in your writing so go for it!we need excellent and talented teachers to lead the way!!!GO FOR IT!!!
