"Tienes o jos muy bonitos" should be:
* "Tienes ojos muy bonitos" which means "You have very beautiful eyes."
Explanation:
* "Tienes" is the correct form of the verb "to have" in the second person singular (you).
* "Ojos" is the plural form of "ojo" (eye).
* "Muy bonitos" means "very beautiful."
Here's a more natural and common way to say it in Spanish:
* "Qué ojos tan bonitos tienes!" (What beautiful eyes you have!)
