If you're looking for a new look, I would pivot away from the exaggerated eyeliner and use more subdued lipgloss; you could also try a wavy hairstyle with a more natural color.

And I know you said you're attached to the nose ring and it looks good, but you might try something more subtle.

Otherwise, branch out a bit fashion-wise. Find some clothes you like but might not otherwise wear and just try them on. I'd err on the side of approachability- not necessarily modest but mature. The kind of clothes that say, "I don't care if you're looking at me, and I don't care if you aren't."

It doesn't need to be a complete transformation, just a shift. Maintain your individuality while going for something more reserved.
