In 1990 I was invited by a commercial gallery in Winnipeg to have a solo exhibition. We lived in Kenora at the time, and because the gallery also did custom framing I'd drive into the city often with at least two of our four kids with me to have my watercolours framed.
My paintings were of my own children. I was concerned about composition and about how the sunlight on the figures caused interesting shadows. I used a loose technique of primary colours mixed right on the paper and I used mixed media. When he saw my newest paintings done for the exhibition, the young owner (male) took me aside and advised me to change my subject. He told me that while my technique was unique my subject matter would limit me. He showed me his own work. Dark large abstract oil paintings. I know that he was trying to help me.
It irked however and I thought about what he said for a long time.
I ended up calling that exhibition "What Is Really Important?" .
