Él se ve feliz.
feliz
I'm happy too in Spanish is Estoy contento también.
Estamos contentos.
You mean "Happy Valentine's Day"?
Happy land in Spanish is tierra feliz. Happy land in Italian is terra felice. Happy land in French is terre heureuse.
To say, "It looks' in Spanish takes 3 syllables. In English, when you're expressing disgust, the shorter, the more impactful. So it is in Spanish. So rather than say, "It looks," a Spanish speaker would simply say, "EW! How ugly!" And they would say it, ¡Ay! ¡Que feo/a! (depending on whether the thing/person/etc. is masculine or feminine).
Feliz Navidad!
Hora Feliz.
y feliz con
mujer feliz
Pueblecito Feliz
Felices Fiestas
