For this rose I used a different light. The last two were spot-lit with a "daylight" spotlight that is actually fairly yellow compared to ... the light I used here which is VERY white. I tried a slightly different approach here and waited to put the darks into the flower at the very end. This worked well I think but it was really hard to get a feel for it as I went along. I had to try hard to get the lighter values right as I went, and to trust that it would work out in the end.
