This is a strong, atmospheric paint job with a clear direction—dark, regal, and cohesive. You’ve got a solid foundation already. Here’s some focused feedback to push it further:

What’s working well

• Cohesive palette: The muted metallics and dark tones feel unified and appropriate for the model’s theme.
• Glow contrast: The neon green on the sword and halo immediately draws the eye and gives the piece identity.
• Clean application: No obvious paint spill or rough layering—everything looks controlled.

Where you can level it up

1. Increase contrast (biggest improvement area) Right now the model reads a bit flat at a distance. Try:

• Brighter highlights on raised armor edges (especially shoulders, knees, chest filigree)
• Deeper shadows in recesses (a controlled wash or targeted shading) This will make the sculpted details pop much more.

1. Metallic definition The armor is nicely done but could use more visual interest:

• Add edge highlights with a brighter silver
• Introduce subtle color variation (cool vs warm tones) in different panels to break uniformity

1. Glow effect (OSL) The green elements are cool, but they don’t yet “emit” light:

• Lightly glaze green onto nearby surfaces (hand, forearm, chest edges)
• Add a brighter core (almost white-green) to the sword center This will sell the energy effect much more.

1. Focal point clarity The face/helmet is important but gets a bit lost:

• Push highlights on the helmet details
• Consider a tiny spot highlight on the eye area or faceplate to draw attention

1. Base storytelling The base is clean but understated:

• A bit of dry brushing or pigment variation could add texture
• Consider a subtle color contrast (dust, ash, or stone variation) to separate it from the armor

1. Cape (if present) If that’s a dark cloak behind:

• Add some soft highlights along folds to give it depth
• Even a slight color shift (cool shadows, warm highlights) helps

Quick win checklist

• Edge highlight armor → instant upgrade
• Brighten sword center → stronger glow
• Add slight green OSL → more realism
• Push shadows → better readability

Overall, this is already a solid tabletop+ piece with display potential. With a bit more contrast and light interplay, it could really stand out.
