A peak inside

Thoughts on the framing or the depth of focus--would it have been

better to keep all the veins in the leaf in focus?

I don't think so, Jim. In your composition, both the blue background and out-focused leaf on left are helping us to see middle spot, and lead our eyes to the edge of the leaf. Very attractive colour composition.

Nice contrasts!

To answer your question - yes. Color and detail of the in focus portion of the leaf as well as color of the sky are really good.

You have some nice nature macro work here, but I don't much care for this one. Some nice component parts, but the net effect for me is "so what?" I like the detail in the leaf and the backlighting. I also like the blue black patchwork to the right, but I find the out of focus portion of the leaf highly distracting (of course, you eliminate that and you lose the nice background). Also, the overall composition seems off balance: too much leaf? too many elements competing for attention?
