Having taught art and the critical process all my life to both children and adults I am well aware of what it entails. A major part of my degree was in just that.
What I mean here is that I am reluctant to make such comments to my superiors in the field, (although of course I am happy to receive them.)
And actually, as I mentioned higher up this strand, if you are just starting it must be pleasant to receive a comment, even of WOW, rather than be ignored completely.
