I would say just ignore this individual. It is a troll or perhaps a SNOT, but certainly it is not someone who has much knowledge about art. Personally I like how you have used blue, green and gold with the black. I probably would have enlarged the frame so that the composition shows all nine sides of the three 'rings' but that is just a personal choice on my part. I have always liked your work, don't let this person get under your skin. BabaLouie
