The reason I don't LARGE face-on photos of family over the fireplace is it just seems like I am being stared at, lol! On the flip side, I covered my mantle at my old house with SMALL photos in ornate frames of friends and family members. Then a large picture/wood block print I loved in the center. I had wall mounted lights that looked like candle sconces on either side of my art, something you might consider., (either the lights or the sconce, well out of the way of little kid hands). That corner curio cabinet is GORGEOUS and I would put something on the mantel with a brown wood tone to tie in with the cabinet. Maybe a picture with a brown frame or some art with some color in it including brown. Or consider adding some colorful art or something on the wall kitty corner from the fireplace, so the room look a little more balanced. I don't see anything wrong with the sailboat photo, but then we are sailing people and love boats and the water and have spent considerable time thus engaged. If you're land-locked and have no association with boats, then it is a little contrived but will do until you find something that speaks to you. If it were me, and I had traveled the world, I would want pictures of that somehow. I have a large travel advertisement picture of a famous place I visited (Valley of the Ten Peaks in Canada, which is often used in Canadian tourism advertisements) which hung over my couch in the living room of my last house, and was surrounded by some other art pieces evoking the northern Rockies. Which made the space feel welcoming to me. Not saying you should copy me, but just sort of showing how you can develop a theme of stuff that reflects your live and loves in your "living" room.

I have a Simple Human mirror for detailing. I have the small rechargeable one that folds for travel. I leave it on my counter and hold it up to my face when I put on mascara. I don't have a sit down vanity. I am not an extensive makeup user, and this works for me. The lighting is good. I have never tried to accommodate different lighting for my makeup. That's too much to ask of me, lol.

What other lighting will you have in the space? Also, your ceilings are much lower than the inspo pictures, and the desk is set up to have the fixture fall over it, ( not intrusive). are you keeping your current setup, are you adding additional task light, etc.

It's not hard to pull wire from the existing switch or outlet box to a site of your choosing, so that you can have the fixture you want in the place that you want without wires showing. If you're uncomfortable doing that, hire an electrician-- it's a small job.
