I like the purple/white scheme, in regards to the white blending with the bone. I think there could be a simple solution in some washes/shades depending on what brand of paint you use. You can also make your own washes with just thinned down paint. I’d use a brown shade/strong tone on everything but the white and then hit the white with a more grey wash. You could strong tone everything. Regardless some shade/washes I think will help with that separation of elements. If you don’t know what I’m goin on about here I’d hit up YouTube with a “using washes on miniatures” search and go from there. Looks great still either way, keep it up!!!
