Gotcha, I think if i post the diffuse texture map you will see there is alot of different color inside the texture. But think the overal lighting is too aggressive together with the color correction. And then maybe the amount of different coloring in the diffuse isnt as strong as it looks.
Maybe try flipping the green (and maybe the red) channel for your stitch normals. They look embedded in places, but the normals seem to be outside the string, which would speak against them being inverted, but it's worth a try. Maybe just calculated from a diffuse? Perhaps you can show the normal map and diffuse for some…
Sorry I was away for a week and afterwards caught a flu. This is the normal texture for the leather parts: Don't mind some overlapping parts, some tiles aren't used anymore / changed. I need to clean those up. But the stichting parts are definitely too much in the normals? This is the diffuse texture for the orc:
