A good 9 from me. This is very useful, and show good research. But I have to agree with GIBasttiste about the out of focus shots. Correct these and you get a 10 from me
Good explanation on the colours you have used, but I have to agree on the photo problem.
I'll give your tutorial a try, because I'm working on my nmm skills and haven't figured out how to get copper done.
Unfortunately I took all the photos as a batch and when I came to writing the article I noticed that some were out of focus
I'll probably replace the pics sometime in the future.
great to see this as have been trying copper and bronze my self for statues and could never get the copper right, a tut on gold and metal for armour would be great as well. keep up the good work,
