Well, no with adjectives. "Es bonito para María" would be the correct sentence. But the other are correct. ps: "es bonito para María" means: "It's beautiful to María" , so, María finds it beautiful. Another example would be: "Este vestido es raro para Julia" that means: "This dress is weird to Julia", so, Julia thinks this dress is weird. Well, I don't know if it helps, but I hope so. Bye c:
