I see you still have a connection between the base body-texture and the Specular Color. That may be redundant when the Specular Color is black. I think you may also get better results by replacing it with the Blender output. Also, your Image Map 2 could be replaced by the Image Map 3, with adjustments to the Bump value. Set it as a negative value, and a bit less magnitude. Instead of 0.100 try -0.05 A seperate map will let you make hems, seams, and waistbands, so it's a trade-off. Also, see if Gradient Bump or Displacement do a better job.
