This is something quite different from what I've seen recently so alone on that it stands out, and the end result is not only more original, its also quite beautiful. I think Helm's edit make the lips look a lot smoother, but somehow it ended losing some of its charm, maybe it's the fact that she lost the mole? Maybe you can save the mole (make it a bit softer perhaps) and tweak the lips' shading a bit? Also Ptoing's little changes to the AA are a nice addition. The piece is very clean as it is, but in Ptoing's edit it ends looking even more smooth.
Top notch work Panda. Very inspiring! Thanks for sharing.
