Blemish and scratches tutorial

I have been asked for a continuation to my armor tutorial, regarding blemishes and scratches. I don't know how good this covered the desired subjects, its more like a "how I do it" than a tutorial but I do hope it will help some of you. If you use it, maybe post a link to it under your work and I would surely enjoy a link to your image to see how you adapted it to your needs. Happy holidays!

P.S. Do let me know if there is need for clarification on the subject or if there is something that could add to the tutorial.
