I think the dark one is a better fit with the cabinets, but maybe too thin? The other one has awesome texture, but maybe too much with the wall? Should I put anything at ends of mirror, ie. Small shelves etc?

The dark one stands out better and also ties in with your beautiful kitchen. Well done!

Do you really want to see a reflection of your kitchen when you look in the mirror? It is a nice kitchen, but a decorative mirror should reflect something interesting, like a view of the outdoors. Your travertine wall is beautiful!

The frame on the larger mirror is too narrow. The smaller mirror with textured frame works much better on the wall. It isn’t too much texture, since the scale of the texture is so much smaller and the color or the frame uniform. The height you had mirror in photo looks perfect. Hang mirror and do not add anything else to that wall - it would only add clutter and detract from the focal point (stone). Great job on your kitchen and DR!

I like the grey mirror; I would put a shallow long glass or wooden bowl full of a fruit like apples or pomegranates in front of it. It's good Feng shui to have this arrangement.

My first reaction is that you need a large piece of modern art there. It would rock the room and add some color. Lovely space.

Love the grey with the thicker frame.

I would either do a large colorful art piece or get three mirrors and space them out accordingly

Vertical mirrors not horizontal

Also your table needs to be centered under the light, even when you get a new one if you do, if you keep those chairs consider moving the end ones to the sides as well in order to center the table under the light and have room on the ends to walk around

Your kitchen is gorgeous I wouldn't worry about that reflection at all
