I still have a little more left to do, but it is now nearing completion. I will work a little more on the white petals - trying to pick up some rose and yellow tones. Even though it is a white tulip, there is no pure white on the canvas! The white petals are mixed with other colors, but they look quite white in comparison to the silver/gray tones of the shadows.
My paint is applied rather thinly - and then glazed back with various tones to get the shadows. Also I glazed the center of the flower with some deep cadmium yellow and alizaran crimson to get a depth of color around the middle. (I use Liquin, fine detail, mixed with a little pigment. This has to be applied over another layer of paint.)
Well - I should post my final version soon! Keep watching!
