Here's the first original:
For this image I used Lightroom's radial filter to select just the leaf, then desaturated the rest of the image.
And here's the last original:
Starting with a Post-Crop Vignette (-18), I then increased the light tones (+30) and decreased the dark tones (-20). Next I increased the Yellow Saturation by +93, then the Highlights (+100), Sharpening (+125) and finally Luminance Smoothing (+100).
Needless to say, a few other people (and species) beat us to the beach.
