a lovely portrait. super composition and exposure. my one quibble is the eyes. the USM has made strange little sparkly things in the eyes, like they're filled with shiny dust.
i was getting tired of usm doing that to me, so i took what i'd read somewhere inthe forums and applied it to my work:
duplicate your background layer
do a high pass filter at around 10 pixels (or more, it's up to you)
blend option that layer to soft light
alt+click on the mask icon to create a complete mask of the layer
paint in just the eyes.
this will sharpen them nicely
duplicate background layer again
blend option screen
alt+click layer mask
paint in eyes
adjust opacity until don't look freaky.
this gives the eyes a little more light and oomph.
This way keeps the appearance of the real texture of the eyes.
I like the expression that you have captured. The eyes (iris and pupil) need to be much clearer however; I think post-processing altered their appearnace.
Whoa, dude needs an eyebrow trim haha. Actually I think those covering his eye kinda distracts from the image a bit. These kinds of portraits are huge on the eyes, they make or break the photo.
