The girls agree with you. They like the path shot, and I think we can have the pair of this pic blown up and framed. They also wanted a bit of family, so I found three similar shoulder on head shots, of the girls with their father, grandmother and then an old pic of their father as a child with his mother. The poses are similar, and I think I would frame them and put them along the top.

The mirror is the wrong size for the mantle. There was a Houzz article some time back on sizing mirrors above fireplaces. First, you need to decide whether you want a mirror, a large picture, or a collection of objects on the mantle. For a mirror, it would need to be much larger. The upright edges of the mirror's frame should be the same width as the corbles under the mantle. The bottom of the mirror should be at least 150mm above the mantle and the top edge of the mirror approx 200mm below the cornice. Working with what you have got, try turning your existing mirror so the long edge is across the chimney wall and at least 150mm above the mantle. Petapea's idea of a round mirror is great and will alleviate lining mirror edges up with the mantle or fireplace. Otherwise, try styling the mantle and wall with assymetry. The sofa is out of whack with the other chairs/furniture given there does not appear to be a TV in the room. It looks too big for the space and is pushed up against the wall to fit it in. A large 3 seater sofa with feet similar to the chairs would be better. The sofa would then be visually smaller, there would be flow around it, and it would make the space look bigger as you will see more floor. Do you need a rug? Get rid of the rug or get one that fits under the legs of your "new sofa" and the other two chairs. A glass top coffee table with silver/bronze legs will be more sophisticated and make the space look larger too. Good luck.

Although a round mirror might be a great artist/attractive choice looking at lighting in your bathroom mirror with lighting would be a better choice if you search Houzz for bathroom mirror with light their were some great designs Pendant would not help when do makeup or beauty routine You wouldn’t need those other accessories to make it fit in - more money for something elde

Keeping it all the one wall colour is more modern as per the pics. My earlier comment was more traditional. Either mantle or mirror or pic frame above could echo kitchen. White corbels. But rather than wall colour for mantle, if you aren’t going black, I’d match the architraves to help it pop just a little. This would be my preference.
