Re: Masdevallia bennettii
Lots of color and depth in that flower!
Evaluating the image, I notice some ghosting -- like two or three copies of an edge, some sharper than others.
This is most evident along the edges of the yellow parts, just above-left of center, and in the purple hairs along the sides of the petal, bottom part of frame.
The most likely causes are (1) real movement of the flower between shots, or (2) apparent movement of the flower caused by changes in lens position as the stack is shot.
I cannot tell from the image which of these causes (or others) is responsible for the ghosting.
For people who are still learning how to do focus stacking, I often recommend to practice on subjects that for sure will not move. Ideally the static subject will have geometric features and complexity similar to the subjects you'll be shooting after you get the process dialed in. In your case I might suggest a pile of small rocks and pieces of bark -- things that will have both crisp features and places where foreground overlaps background.

Re: Masdevallia bennettii
You are correct in that assessment. I believe that the problem was the later, as the flower in this case is quite fleshy and held tightly on the flower stem. I need to work on my photographic technique a little, as well as software use.The most likely causes are (1) real movement of the flower between shots, or (2) apparent movement of the flower caused by changes in lens position as the stack is shot.
A lot of small flowers have incredible detail, which is why I'm working on mastering these techniques.
