Hey Chris! Thanks for the comment. Yeah it's a print. It can be found by people who print and sell figs (Etsy). The STL, or print files are no longer available due to GW sending the creator a DMCA notice.
As to the colors, there will be more. Truth be known, there is more to it, the posted pic, while looking pretty good is actually a really poor pic. The colors are way off in it. Should get my camera back tomorrow. I have so much more to do to the Angel, at the moment I'm just trying to edge highlight all the details. ALL the details, so many. If you look at the right forearm you can get a feel of my base coat, I haven't gone into any edges there yet.
