I agree with post above me. Not enough done. It would of been nice to see you fix those stray hairs & fill in the gap where there is hair missing. The neck and the cheeks seem to have too many splotches. Doesn't look like the rest of the skin. Could of defined the eyebrows. Added too many shadows/contrast. On the right side of her neck on the background I can see where you edited out her hair. I'm sure there is more...but keep practicing and on something more simple that doesn't need many things retouched. Then build your way up to something like this.
Yeah, this definitely needs some more work. I agree on everything said above. Overall challenging photo for beginner. Needs d&b, background fix, hair fix, eye fix etc. It seems you smudged/blurred out skin a bit.
Keep working hard and you will get there
Enough for what? Informal portrait in a family album? Cover of Vogue? Billboard 20 feet tall? Thumbnail on a Facebook page?
I think it was just a general question. No need to discourage a beginner.
You definitely picked a challenging photograph to start with. It's not that you did a bad job or didn't do "enough" per say, I think maybe you just don't possess the skills needed to tackle an image such as this yet.
Some more studying and lots and lots of practice will help get you there though.
Just keep going go further into the retouch. After cloning/healing it might look blotchy that is fine just keep going, now d&b it. I like to use the clone stamp and heal very little (sometimes eyewhites and hairs on side of face to get that spreading of color) and it looks a tiny bit blotchy after I am done cloning (I clone with the darken and lighten modes) but after I d&b it looks perfect at least to me and to my employers. You want to turn the layer on and off and have stuff disappear not having pixels running all over the place. You will get if you work at it don't give up.
