Lovely image. It is is hard to get all the flowers in focus, so stacking is a good choice and has worked well. I have a few images of these and they suffer from shallow dof even with f/16. These are just above ground level, so getting the right focal place is also a challenge. very well done. The subtle gradation of yellow to orange on the flowers has come out well. Great background as well. dew drops are a plus.
Super shot, I have an alternative for your consideration.
Not sure why six stacked images at such small aperture? I would have gone for something like f4 -f5.6
