This next photo shows the painting as it looked after all the miskit was removed. It was easy to see that some major corrections had to be made. The lower left flower was misformed badly (cropping may help,) and the lower right one needed less value changes from the darks to the lights (adding color to the whites would help there.)
The inside of the main flower needed to pop a whole lot more, and the warmth in the background was stifling and dull. I wished then that I had known to pour all cool colors for that last pour. Too late now - and I wasn't going to re-miskit the whole painting. Also, I felt the flowers needed a suggestion of a stem or two.
This photo shows some of the corrections. The center of the big flower still needs more pop, and the background simply must be cooled down, (which I did NOT want to do.) But it was robbing the sunflowers of impact because it was too warm. Cooling it down with Indanthrone, if painted on in a juicy - poured-like manner, would help give some relief and rest for the eye from all the heat.
Leaving some of the background showing as the stem for the lower right flower would help to anchor the flowers - see the top finished photo. Does it need another stem from the top flower to angle off to the left?
The reference photo above seemed better flipped sideways. Minor adjustments were made for better positioning, etc. before the drawing was completed. Though I seldom paint flowers anymore, this was a good challenge.
