Thanks Alex, the problem was Diffuse map. has no padding so i just changed background color of my Diffuse map (was black). i also changed the lighting, i think looks better now.
not sure which map it is in your turnaround (normal, or diffuse), but I can see the seams. Have you tried blending them together in ZBrush and re-normalizing them in photoshop? Everything else looks great but if you can get rid of those seams, it will really help this one.
