DRAGONFLY ON A SAWHORSE

I'm a beginner when it comes to stacking images for increased DOF, but here is an attempt based on several shots of a dragonfly that landed on our sawhorse yesterday. Afterwards I saw that either the wings or the head where out of focus. In the stacked image, there is only one wing tip that is completely out of focus, though the right wing isn't absolutely sharp. I think it might be worth learning how to stack images. Edit: I should add that the software I used is Alan Hadley's CombineZM. But I have only begun scrapping on the surface of what that software can do.
