A fine image, John. Excellent detail, tone and colour and near perfect background. The only thing I'd do is remove the oof dark blob in the top left, but a very minor issue.
Hi John - For me this is one of the best that you have posted. The tones and colors look good. The comp and dof work well. Nice complementary bg too. Yes, you could even out the bg if you are so inclined but not a deal breaker for me. The only thing I might do if it was mine is back off on the sharpening just slightly. Nice one.
Hi John a lovely side profile portrait .
Good colors and tones , might watch the blacks .Subject well separated from the BG .... i do agree with Rachel that this is one of your best postings from the technical POV .
Keep them coming .
Wonderful portrait Jon, you must be really pleased with this!
Nice colours and tonality, good detail, framing is great. Agree with Andreas and Steve, a little contrasty in places (eg. tips of the ears), easy fix if you like. Subject stands out so nicely against the BG, lovely head angle too.
I certainly enjoyed viewing, one of your best images from what I have seen - very well done
