Makecourtesy,
Welcome to RetouchPRO! Good luck and enjoy your time here. Ask many questions!
Yep, her hair is a different color..
For Tats you might want to look into displacement maps or try this Tutorial

It would be nice if you post a less than 100K picture here so we could click a thumbnail preview and wouldn't have to go off site to evaluate your retouch work. That would also insure that in 5 years from now your work would be still viewable even though the link to it off site may have disappeared.
