Shady areas lifted nicely and sharpening efforts look good. I'm assuming the four central figures are the main subject, in which case I find the ones to the left and the tree trunk impact on the right somewhat distracting. Wondering if application of the "Darken/Lighten Centre" filter in NIK Color Efex might overcome this - I've found it a useful tool in these circumstances with a much more gentle impact than any of the vignette filters.

Perplexed. I can't notice any difference between this and the original; what am I missing?

Not the colour I'd have thought he'd choose, especially as a one-off commission; a vivid red would match his ties better I'd be very happy with the blue though. I wonder what he sold it for.

A couple of nice eagles to snaffle ... ?
