There is a lot of experimentation on this model.
The Armor was sprayed Krylon Bronze the details were relatively shallow so the armor was black lined to add depth then highlighted with Citadel Shining Gold (a very pale metallic gold) and washed with Seraphim Sepia.
I'm torn between calling this "The Babble Cloak" or the "Cape of Incoherence" The free hand started out as some patterns that resemble, but are not actually, a script. Then some larger characters, and some that are not quite actual characters but could almost be several characters. Basically its nonsense... which is kind of what I felt about some of the game rules at the time!
Adding the freehand midway through the red build up resulted in some partially buried lines which was a desired effect.
The freehand was an experiment with cool highlights and warm highlights. The characters are lines with a bright orange in warmer zones and with a pink in cooler zones or shadows. The goal was to make the freehand mildly 3D in the top (warm) zones and to get it to stand out legibly in the shadowed (cool) regions.
I'm getting interested in shadowed highlights, and it needs a lot more work, but I learned a lot and I'll refine it as I go.
The white areas were Graveyard Earth (Reaper) over the Krylon Bronze, layered with Splintered Bone (Reaper) shaded with a very dilute (50-50 Shader and Glaze Medium (Vallejo)) Military Shader (Army Painter).
For size the Herald faces off against the Dancer... this may not end well..
Next up are the Centaurs!
I'm continuing to work on warm and cool highlights with them which is giving a some really interesting Light and Darkness interactions.
