Are these the final images? (Please understand if these are images for competition like the Contessa awards I am going to give a strong critique)
If so I think you need to re-work the skin for each of them, you need to remove the skin blemishes, and there is something going on by the lips/nose of the 2nd picture, looks like bad cloning.
You need to get a hair light, Something soft to put overhead to give better lighting and shine control. I am willing to bet there are alot more tones of red in the last photo than we can see, it looks like just solid red with very little highlight, as well a softer hair light over head will give better texture definition, especially in the 2nd one.
PM me if you want some tips on photoshoping hair for competition.
