"ashes the contractor to remove all if this. So how the mirror tiles are installed correctly?" "I did but didn’t pay attention to this" They appear exactly how I would expect mirror tile to look. You did not do your due diligence and know what you hired him to do, not his fault. Pay him to tear it out and reinstall what you want. Unfair to expect him to do it for nothing because you did not understand what you asked him to do.

rugs are too small, there is no entry light (that I can see) instead of a mirror, do some colorful art, the bench could be better, instead of the tall tree, do some hangers on the wall. (i'll post examples of those) paint the wall and the door a diff color. The entry has no pizzazz. give it some Like this. your mirror is too small and too high. redo the entry like shown here or, try some contrasting elements like this charcoal jute runner, dark console, style it w/diff elements, maybe do a board and batten wainscot, paint the door, etc. plenty of space to hang things. painted door, wainscot, bigger rug, light bring in a runner w/some life and color. ditto a hanging light don't know if you need this much storage, but this is an idea art longer bench, larger mirror, a plant, some wood accent on the ceiling and a diff rug. easy fixes

I have a mirror addiction. Placement is key. There are no steadfast rules. I think it is more about how you are reflecting the light or architectural interest of the room. Can the mirror hang on the west wall to the right of the door? If so, it will reflect the light coming in the window and the view out of the window. It will almost serve as a second window. Hanging it above the sofa just reflects the flat wall across from it, which doesn't really add much to the space. I think it is fine to start with a piece of artwork or a mirror as the first item in a room around which to anchor your other furnishings. The layout of the space does look like an uncomfortable waiting room. Who is going to be using this room and when? Is it an additional sitting room or your main living room? Are you wed to this furniture or would you consider swapping the love seat for an arm chair or two?

We used SW Aesthetic White in our house with lots of windows. Have not yet seen the "violet undertones" that SW says it has (a good thing!); it is very neutral in all lights.
