maybe I said it wrong......I agree that a student may have style even with learning techniques. In fact, some of my students have very distinct styles. However, the problem arises when they use it as an excuse not to try to learn other things. At this point in their art "career", I feel that they need to be open to all sorts of media. I once spent four years trying to get a student to try something besides pen and ink medieval scenes. Turns out that he was successful in other endeavors.
Maybe I'm such a strong believer in technique because I was such a stubborn art student!
