This is excellent! There is only 1 particular thing I personally notice, (you are FAR above my ability at this) I would point out, in the retouched version, where her hand on her head used to be, you can tell where the source of her hair originally came from. I would (personally) have added a different light source there, or maybe took from multiple areas to make a whole. I hope I did not offend you it is only something I notice, but otherwise AMAZING WORK!
I am happy you are not offended Practice makes perfect! and I am far from it! lol! I have no drive to even do art lately it is a real bummer. I keep coming here to try for inspiration, but my mind is like a sieve and wont hold a single idea!
