Hi Susan,
I wasn't sure about the crop and also thought it might stand a little more 'punch'.
How does this look?
What did I do? (and why)
Opened in ACR;
Clarity: +30 (add punch)
Vibrance: +15 (ditto)
Shadows: +30 (reveal a bit more detail in shadows)
Opened in PS CC;
Cropped some off top edge (to just exclude the off leaf are in top right corner which I felt was unnecessarily attracting my attention too much)
Downsized to 950px tall (to fit most people's screens better at 1:1)
Sharpened with USM at Amount 150%, Radius 0.3px Threshold 1 (sharpen necessary after downsize)
Saved as jpg with level 9/12.
Any better? - you can flick between them in LyteBox (images 3 and 4)
In hindsight, I might also crop a slither off the right hand edge as well, just enough to remove that green spike, as that now attracts my eye.
I didn't ask whether you mind me reposting an edited version of your image - if you do, let me know here - and I'll remove it (but leave the editing details)
I hope that is helpful in your quest to "learn, learn, learn".
Cheers, Dave
