As promised, I sent a digital image of the draft copy of the painting to my client, who was delighted and felt sure that his wife will love it!
A painting always has to sit for a day or two, and that allows you to see it with a more objective eye. I noticed that the draft copy composition was too cool, being largely blue and green. I also felt that the values were too much in the mid-range, so I strengthened some of the darker tones with burnt sienna. I also highlighted the leaves with some of the light blue that I had used around the flower.
The composition looks more balanced to me now, in terms of both color and value. And the client is delighted, so this painting is good to go!
Even though the original is already sold, prints can still be purchased through my site on etsy.
