Here is the top down view. I accented the worn parts by using a tutorial that I saw on how to make bullet marks. The process is really simple. Free hand the area you want to have the mark with black then fill it in, leaving a small area black, with boltgun metal. Then a final highlight of mithril silver to get the final new metal look. Works out great, just don't go overboard like I did the first time.
As soon as I can get the Deffcoptas to a point that I like I'll post them up as well
