そうですね。In japanese is not usual anata or kimi. Anata and kimi is use by husband/wife and boyfriend/girlfriend. In your case, you must know the name of your partner language. Like 田中さんほど上手じゃないですよ。but, in my opinion, don t sound natural this awnswer. Maybe it s more natural if you answer, そんなことはないです(im not so good that you think), or いいえ、まだまだだよ.
