Need help for nodes settings in Cycles

Hi everyone!
So I have a problem since a moment already, I work on a Xnalara model and I wanted know what is better way for have a model with detailed textures?
Actually I’ve tried some nodes settings but I’ve not really the result that I want, I think it could be more detailed but I don’t know the good way for, so that’s why I ask some help here, if you need some precisions just tell me, thanks!

My crystal ball is broken and the local clairvoyant caught a cold.
Can you post a .blend file, with examples of the textures you need?

Lol, alright no problem I will post the .blend file, there :

And I will post you the file that contains the textures, there’s just the textures with their normal map : https://www.dropbox.com/sh/obhsk21wcy8euf4/AADJes58-hLgSuz0yOKMX_H0a?dl=0

In the .blend file I’ve already placed the texture and the normal map on the shirt material, above it’s the texture and below the normal map
