So far it looks fine. i would select a mirror that is centered over the sink. Now the only issue is where you placed the lighting above.

Since your cabinet doors are not centered, it is only noticeable if you look at the sink and counter and see a bit more room on the left. Not sure most people will notice, and it saves you from “perfection,” freeing you from having to meet that standard.

It looks fine. We notice these things at first, but trust me, you’ll never think about it again lol. What kind of mirror are you doing?

It really does look fine. I wouldn't give it any more thought.
