Your translation was very good. You miss spelled a word & repeated a word. Other that you were quite good. Krystal is the perfect spokesperson for Hi-Mart. She is cute, friendly and very popular.
I left a word out myself in my comment. It should read: “other then that you were quite good”. See we both made mistakes.
