I looked at the large-sized file on Flickr. There appears to be no skin smoothing at all, just areas where the depth of field doesn't cover small areas of the face. Otherwise, the pores and minor skin variations appear straight out of camera. Catchlights also appear to be natural, when seen large enough to "see". However, when reduced in size to TPF's dinky max size, the file's overall look is basically, destroyed.
My issue is that this is like the third vertical portrait you've posted within the past week with the subject awkwardly positioned well off to one side of the frame. This unbalanced, unsettling, off-centering of the subject looks very "affected", to put it politely. In this shot, the head-chop in favor of including more of the scoop necked T-shirt makes little sense to me. The majority of the things that make this shot are simple, and natural,like her simple hairstyle, simple makeup, and direct and "real"gaze.... and then there's a head-chop...it just doesn't work.
