Here is a recent edit that I did. This work just for practice. What would you advise me? This is my fifth baeauty retouching, fashion, etc.

I like everything you've done here, though i might bring back some of the detail and tonality
of the jewelry on her hand.

Nice and clean, a bit too sterile in contrast with a quite visible, deep wrinkle on a wrist of her hand and the thumb (to be picky), but you did a really nice job on her skin, and you didn't overcook it. Nice work with the hair. The colours seem to be a bit washed out and I'd probably add a little more of contrast, yet in your portfolio it looks all right.  I like your taste. Would be nicer if you didn't put 'befores and afters' next to each other in your portfolio, so your own work can be more visible and speak for itself in higher res. It's really not necessary to include 'before' image, and in 'Location' info under the picture you can paste a link to the post with the original one.

Good luck : )
