Really looking at art!

I have found that I am not enough to critique Bill's art work any longer. I went to a great discussion given by some local watercolorists. They work as a group and are able to help each other out. I am not an artist and as Bill's only one to call for opinions I feel I am lacking. He needs a guild, a group , cronies, someone who is an artist to bounce his ideas off of. His dad would be great! There are some artists in his building, maybe we need to be friendlier so they come by and offer opinions. Maybe he should have a supply of cookies on hand.
