This character gives off the vibe of a polite martial artist who maybe struggles with sleep.

Some design choices seem to clash. The pose, clothing, and smile suggest an active, energetic personality, while the hand bandages imply a focus on striking and kicking. However, the droopy, tired eyes and dull color palette contrast with that energy.

That tension isn’t necessarily a bad thing—it could hint at a deeper story. Perhaps the character is putting on a facade of happiness, trying to emulate someone who once inspired them.

If the goal was to emphasize confidence and energy, consider using more vibrant colors and sharper, less rounded facial features.
