那是别人的才华不是你的英语怎么说

It's other people's (artistic) talent, but not yours.

It shows others' literary or artistic talent, not yours.

才华 [简明汉英词典]
literary or artistic talent

That artistic talent belongs to others but not you!!
Itis others artistic talent, but not yours!

其实有很多种说法，都可以的，大家说的都对哟~我在外企，刚请教了老外和一个专业口译同事，觉的最地道的、最简单的说法是：That is other's talent, not your's.希望可以帮助到你，谢谢！

That's other people's talent, not yours

It is not your talent, others！
