I ran this through ACR to bump the contrast to +32; vibrance to +8 and saturation to +12. It looks good.
Nice texture. Hmmm, yeas, a little bump to the red would be interesting. ( and how you do it, or does Izzie have it figured out? )
I have (new) PSE 11 and on big learning curve.

Thanks for looking and commenting Isabel.
Here is another version where I selected the red leaf in Lightroom and muddled about with the various sliders and tools to increase saturation. LR also has a color picker that allowed me to shift the color of the leaf. I need to learn a disciplined approach to this as I was mostly just pushing sliders and things about to see the effect. I didn't change the yellow leaf. I thought the color of the two leaves against the textured shell background was kind of neat looking.
Nancy....as you can tell I've not much skill with the post processing. A bit of a prayer and wing it. Plus, I don't have any notion of how this is done in Photoshop. Thanks for looking and commenting.

Nice effect Andrew. I would suggest a tighter crop to bring the leaf to a more central role of "star of the picture" as it is your main subject. I like the repetition of the patterns formed by the shells.
Bump works great.
