Translation guide
In Japanese, expressing that something is praiseworthy depends on the nuance: whether you're admiring an action, praising effort, or describing something as admirable. The most common and natural ways are 立派 (rippa) for general admirability and 感心 (kanshin) for being impressed by someone's conduct.
I'm impressed (by your effort).
