I don't mind the redish tone - now that you show a red hair style I've seen real people that had skin ton like that. 

as your testing your skin try extreme hair colors and styles.  You'd most likely like to have your texture useable in a lot of varied situations and not a niche.

the eye texture you have going is a bit strange, try differnt eye textures too.  You will start to see problems arise.

also try rendering with 2 or 3 of your favorite light sets to see how the texture is holding up.

looking forward to seeing more.
