Your English is very good. Where did you learn it?
ご質問どうもありがとうございます。
一例をご紹介します。
｛英訳例｝
Your English is very good. Where did you learn it?
英語すごくうまいね。どこで覚えたの。
↓
Your English is very good.
あなたは英語がすごくうまい。
Where did you learn it?
（それを）どこで覚えたの。
｛解説｝
「上手」はいろいろな言い方ができますが、very good が無難だと思います。
excellent も「すごく良い」という意味ですが、主観が入ります。
｛例｝
【出典：The Sensualist by Barbara Hodgson】
’Your English is very good. Where did you learn it?’ ’In America. I lived there as a teenager.’
「英語上手ですね。どこで覚えたの」。「アメリカ。10代の頃に住んでたの」。
