“我认可你的表现”英文怎么说？

如果是口头对话，那么"Good work!"" Good job!"" Well done!" 再好不过了。
如果是书面表达，那么"I appreciate you performance""I recognized your performance "就可以了。

I personally approve your performance

approve：认可，认同
performance:表现

Good job

I appreciate you performance.

i recognized your performance personally.
