It would be interesting to see, as a comparison, a single shot with stopped down aperture , just to see whether it's worth bothering with focus stacking ?
I got this in mind because :
# it seems the subject is not so close (to be confirmed, though) hence a sufficient DOF;
# we are in the critique field and so, I try to find out whether a special technique such focus stacking is really needed.
That said, I like you image , but is it really thanks the focus stacking technique ?
I have to add that you focus stacking is successful as I can't notice any artifact.
A question : did you shot with fully open diaphragm ?
Cheers, Francis.
