The mouth looks weird and the face looks kinda unnatural.
I think there is something odd on the hair to, but I cant point it out.
other than that it looks very good ....and she's hot!

Hi again, I just checked the original that I haven't seen before.
I think that you portfolio is coming nicely.
What I don get is why are you retouching already retouched pictures or pics that does not need retouching.
That model is not "perfect" but if you try to work on something that is quite ok you are pretty close to overdo it, sort of an overkill.
If your portfolio is for demonstrating you skills, then try and consider to present some serious (or impossible) changes so people could really appreciate it.
cheers
