Thank you very much!
I undercoated in grey, then I painted the body first: VGC Earth for the top and VGC Bone for the belly, in between I blended the two together.
I painted the plates Citadel (old) Ruby Red and painted red stripes over the body as well. I blended the red stripes with the body colour. I then washed the whole body with Citadel Gryphonne Sepia Wash.
Between the red stripes I painted dark stripes with Citadel Badab Black Wash.
On the scales I painted lighter spots and edges with Citadel (old) Blazing Orange and then Citadel Sunburst Yellow. I painted the inside of the spots black. Then I painted horns and nails and such black with VGC Earth/Bone highlights.
It was a real pain to put together though! All those scales are separate so it's 23 parts in total. Luckily I had already assembled it long before the league and it had been waiting for a paintjob forever
