The models

A beautiful result, Wim!

Thanks Ruud.

This is a beautiful shot, as is.  The long lens adds a bit of atmospheric haze to the image and reduces the contrast slightly.  I wanted to compare the difference between your original and an adjustment with a bit more contrast on her (leaving the contrast untouched in the background) and dodging her eyes a bit.  I used the history brush in photoshop to return some of the dark areas to the original tones.  This sort of thing is a matter of personal preference and not so much a matter of improving it up technically---more like moving it sideways technically.  Ah, the thousands of possibilities!  Thanks for capturing the images that photographers like pause and meditate on!

Thank you John.

A bit more contrast is indeed better.

With eyes I am always conservative, because most off the portraits I see the eyes are overdone. Then it looks unnatural. But this is oké.
