Another white beauty Ishbel! The one area I would take another look at is the petal at the top that is seen between the two petals of the large flower in front of it. I think you need more dark in the “v” as you did in other spots. Visually, I wish the top edge of that petal in the back did not almost line up with the tip of the large petal to it’s right. Something to consider- either make the large petal come up a little higher or erase part of the right side of the petal in the back (the right edge curves down more) or add another stamen at that spot which would be easiest and would probably help fool the eye (and there are only four of the six stamens currently showing so it would still be botanically correct).
