Mike, your very nice picture gave me an idea as I found in the fruit cup this apple with it leaf.
Setup is simpler than yours, an ambiance light at around 1 meter on the right above the table top, in the same direction a LED desk lamp placed on the table (without diffuser) + some PP
The direction of light give structure to the leaf.
I hope you accept the challenge

May be I should improve it with a small flash on the stem ?
same apple with walnuts
I removed the desk lamp (and only kept it), the light appears softer (curious, it is a point light)

I'll send it when tinypic wants to work properly
It works and in addition upload were kept
I had time to take another one from above with an extension tube
