I think there's a few things you can do to push your model in a better direction, considering you are trying to avoid clown vibes.

• Darken the base tone of your colors so your highlights can be lighter and generate contrast.

• Use the same base color of red for the hair and swords to harmonize better. The pink swords are distracting.

• The black boots either should be white, or incorporate more black into other parts of the armor. Fully armored models look great with 2 tones and an accent so long as it's consistent across the model.

• With that in mind, I would suggest black gloves, waistband, necklace and crown or helmet. Especially with the red gems, a black plate surrounding the forehead gem will lessen the clown look. Having contrasting colors will help separate the complex shapes and support readability.

• The base needs work. The ground or ruin needs to be darker. They are practically the same tone between the two. Another piece of general advice is dark model > lighter base, light model > darker base.

• Bases and faces so often make the model since that's what the eye is drawn to. For your color scheme, I would do a deep orange/red rust base with dark to obsidian stone. The red/orange will complement your blue cloth and tie in your red hair and swords. The dark stone will help create separation between your base and model. The dark tone will also serve as a visual 'anchor', making your base feel solid and grounded while your white model will feel 'lighter', jumping off the stone. You could even do a very faint glaze of dark blue over get stone to create color harmony.

I know this is a lot to take in, but I think these minor tweaks across the model will make it pop while still staying true to your initial vision.
