Looking better, I drew up a markup of some things that need corrected. You might try to convert a copy to cmyk and try out some of the values that where in the tutorial, they wont be exact but should be ballpark...especially at 6am

I had to re adjust the darks/lights in the levels after converting to get the image so that the CMY values of 7:20:24 would look close. (didnt really mess too much with it but it made the color better)
Her left cheek was too yellow, but after changing the skintone cast it changed has a high bias to magenta. There was also a dark oval on the cheek that needs fixed as well looks like a color correction, next time feather it out
The shirt has a heavy cyan cast as well ( 16%,0%,3%,0% CMYK) You might need to isolate the shirt from the rest to get a good color.
btw the markup was on the first pic.
Hope this helps
