Buy me a Dragon - Texturing challenge RTFKT

I decided to join this 2-week challenge on sketchfab:
I created some materials and textures to do so, like embroidery and old leather, aiming to use them also in future projects or the ones that I still have in progress. I shared the results because I am pretty satisfied and I can see an improvement in my texturing process.
The natural process of texturing lends me to happy accidents and colour variations all the time until I felt I got the right ones on the eyes. The resulting colour combination represents the feeling when you are near Dragon Khan, my favourite rollercoaster.
