I am not that experienced with stacking (I tried out 2 or 3 times) but I think this is a good one. My experience was that the OOF parts were really strange, ugly and flat (I am thinking now it could have been a software problem, I used zerene stacker) . I think your picture shows a good OOF, quite soft. Of course the liking and disliking OOF is highly subjective... I really like the soft flowers in the background because the colors come back inside the drops, I usually don´t get distracted that much by backgrounds (it might be just be proof of my chaotic brain
).
Did you use anything to shift the DOF of different shots gradually? It seems some spots in between sharp drops are missed and OOF..
