thanks to the GunFinish this weapon is able to wear down and patina into a beautiful set of colors, rather than lose its color by chipping away paints.

My personal preference, is to add 'old world patina' (weathering) such as displayed in your linked YT vid. Otherwise, I'll agree not bad as a first attempt.
What kind of environment is this statue in? At the moment it's very clean and polished. If it's out in the weather it'd likely be much darker and have taken on a patina of green copper oxide.
I used the "brass patina" and "ceramic glazed" stock smart materials in Toolbag 4 to get quick textures for this. I converted the PBR texture set into something that will work in Skyrim. Materials in Nifskope 2.0
Working more at it. http://imgur.com/a/u0R4a At this point I've added some slight dirt(?), and a bit of patina-like stuff. Nearly all of the detail is in the specular and gloss, tiny bit of brown for the dirt in the diffuse.
very nice, great design! although, i liked the green-ish dark patina in the matcap, which isn't really present in your material. and: the candelabrum looks quite huge in your screenshot... what size are your maps?
