Idle Chatter - before and after processing
The original image I felt was too cool and flat - had depth of field, but no depth - or something.
Ran Totally Rad Lightroom Preset: Chocolate Rain | Light to add a warm brown tone. Bumped the brightness WAY up.
Added a series of graduated filter brushes from the outside of the image in to create a deep, but not necessarily uniform and balanced vignette (bumping the brightness way up maintains the integrity of the subject as you drag darkening gradients over the image).
Then bumped the clarity up as well as the contrast tone curve to Strong.
