Roses in a Blue Bowl

Somewhere I remember admiring roses in a blue bowl, so I decided to try to paint a blue bowl with roses in it.  My model was actually a white bowl, but after I carefully shaded it and painted it in white, I used glaze and glazed over it with blue.  The shadows can easily be seen through the glaze.  It is an old master technique that I learned a long time ago–paint everything in brown tones with careful shading and then glaze over with color.
