I'd love some feedback on my Retouching

Hi Guys! I've recently started working on my retouching and want to concentrate my time towards getting to a stage where I could possibly be doing High End paid work in about two years from now. I don't know if that is realistic but here is where I'm starting. I'd love to know what I could do better. I am aware that hair is a weak point for me...

Beauty Retouching

Hello there, here is my new work. What do you think about the tones of the edited image? Warm or may be some cooler tones would be better? Please, share you thoughts.
