As a child I once made a piece of pottery and, before firing, sprinkled small pieces of glass in the bottom. The red glass went almost black, which I didnt expect, but the blue and green worked beautifully contrasted against it. Your vase took me right back! Lovely work, indeed!
It's all been said, but I am attracted to the "exploding" look of the flowers although the whole painting is so balanced that one part is not more important than the other, 'the whole is more than the sum of the parts' in this one for me.
