Hey Eric, thanks for your answer.
Well personally me- I would like to see some small pores added to your specular map just to break it up a bit. I know it is a female character and all that but skin is skin. Take a look at the bottom of that page
and you will see what i mean. Does not have to be a lot just very very subtle.
Also since she is a warrior perhaps there could be some variation on the skin ( some parts of the skin are getting sweaty before others and looks more grease and shiny than others - like under the eyes inner section and above/outside section of the upper lips) Those are very small things but I am sure it will make a difference.
