This deserves a 5.5, the paint job is "tabletop" but there's at least an honest attempt at weathering the metal and the freehand emblem isn't bad. The gloss varnish doens't look very good though.
I love Khornate Chaos! Some of the detail work is very good (I like the eyes, but a bit of shading would help) but it all seems too glossy...maybe too much varnish???
