Well, the mirror you have is neither just over the vanity or covering the whole wall, so that's probably why it looks odd to you. The sink is situated oddly in the vanity, I guess to get a larger sink in a small area. So I would pick one - either a smaller mirror that is just over the sink, or a larger one that covers the whole wall. There is no right or wrong answer - some people prefer smaller over larger, some the other. If it were me I would also replace the vanity as the way it is bothers me. But if you want that size sink that might be impossible in that size vanity, so once again, do whatever suits you best.

Many think this solution old fashioned, but I have always like a counterop that extended across the room along with the mirror.

Here is another way to make the room more custom.

Most toilets have an awkward space above. I believe it is a part of the plumbing code. ;) You already have nice art in the room and a designer vanity. I’d leave the wall above the toilet as it is and buy a black tissue box for the toilet + a more upscale soap container for the vanity.

It looks odd maybe because the size of the mirror doesn't quite match the size of the vanity. You can try replacing it with a smaller mirror; If it's inconvenient to keep the light fixture in the center, you can consider placing one on each side.

Professional home lighting offers you more choices.

Start your own thread is the way to help. This isn't your thread: )

Fully mirror the back wall and use a loooong linear light , centered between vanity and toilet

I do not understand the sink/vanity/ angle concept, but that's a different discussion: )

I would remove the tile so it is just a backsplash for the vanity. Take down the large mirror and put the one from the left wall over the vanity.

Thank you all for the pictures and suggestions! Very helpful ...

This bathroom will be getting an upgrade:-) The vanity is an odd relic from the prior owner, so will upgrade the vanity/sink, get rid of the racing stripe, and customize the wall with new tile, mirror and light.

I do think it's interesting that no men weighed in about facing a mirror over the toilet ....

LOVE the last pic Beverly posted.

Ditto, Kate ... That's my favorite!
