I am doing a master bathroom renovation and am looking for advice regarding mirrors and lighting.

1. The mirrors at the vanity are round and 34". What type of mirror do I need to put at the makeup desk for it to work with the rest of the room? Can it be a rectangular mirror?
2. The desk has drawers on the right hand side. Do you center the mirror over the whole desk or just the side you sit at? What size mirror would work best given the measurements of the desk?
3. I chose three sconces to go between the mirrors at the vanity. It seemed like overkill to put 2 more sconces where the makeup area is. I wanted to put perhaps three hanging lights to the right of the mirror over the desk, but this may not be the best option give its a makeup area. What about a mirror with the LED lights for makeup? then would i need any more lighting?

Thanks so much for any advice!!
