help me change it up...please :)...

 

 here are some pics of my home (on a normal day with the family).  so please excuse the clutter, sippy cups, husband's office mess (in my dining room...yes...grateful that he's able to work from home but oh do we need an office space for him!).
please please help me....it all needs some spicing up. 

this above is my living room/dining room.  it's an odd shape and i never know what to do. 

here's the stairway/foyer....
under those ugly carpets you'll find beautiful hardwood floors that just need to be refinished...
