How do you say you are a nice person in sign language?

In American Sign Language (ASL), to express "I am a nice person," you would sign "I" by pointing to yourself, then sign "NICE" by placing your dominant hand in front of your chest with the palm facing out and moving it away from your body in a smooth motion. Finally, for "PERSON," use both hands to form a "P" shape and then move them downwards in front of you. This combination conveys the complete message.
