hi tommy and welcome to
RP.
tough image. i started by duplicating the background and then adding a contrast/brightness adjustment layer.
copy merge and paste to new layer.
usm at about 5/100/5. duplicate layer.
clarify at about 4. duplicate layer.
fade correction. duplicate layer.
shadows/midtones/highlights. duplicate layer.
add a blank raster layer. push, push, push, push, push....rinse, repeat

(push is a type of smudge in
psp). all i did was around the head and shoulders a bit.
red eye removal to add back eyes.
more push.
now, all of that was done to get more definition. i'd probably go back and then color and light correct for all the stuff i did at the onset.
