I'll be perfectly honest - I dont like it. But I'm not one to make such a sweeping statemnt without backing it up

and surely the purpose of this forum is to get critisism that we can learn from.
You seem to be using a technique that I used in my earlier days, bluring the picture then masking in the skin areas over the top of the original - which is ok in some situations but with this picture there are a lot of visible pores and in the blurred/smoothed version they just make the skin appear blotched.
I've attached my attempt (full size) and a smaller version of mine next to yours.
I hope you can see that mine looks more natural.
I acheived the smooth(er) skin by painting over the top at a low opacity, sampling colours from the subjects skin, then adding a little bit of noise to the painted layer to match the photograph.
Other improvements you might consider is that the image is very cold (as someone else mentioned, too much cyan) I gave the original a 10px gaussian blur and overlayed it at 50%, it really makes a big difference to the look.
One other thing was the change of eye colour - you lose all the beatiful tonal differences in her eyes, I chose to enhance the green very slightly but still keeping the flecks of brown and orange in. I also brightened the whites of the eyes.
I hope you dont take this post as being pompous or trying to enforce my style on you. Everyone has their own particular tastes and this is just my opinion. But hopefully if you like what i've done with the image it this post will help you emulate what I have done and improve your own work.
