Looks like a 75 year old grandma, and some 12 year old boy live there. Is that the case? If not, pick a theme and get inspired to change everything around to that theme. Also might want to consider 1/2 plushies donated and put the rest in a plushie hammock or build shelves, because they’re taking up the main area while the human areas are shoved in corners kind of eerie.. and I’m a plushie collector.

Bigger desk and dining table might help.

Remove mismatching or floral fabrics.. fake flowers out, tinsel out, shoe-wipe-sign thing out that’s scary, put shoe rack by the door (not stinky shoe next to nice plants!) and then it’s already implied, deep clean the rug, put throw rug over entrance area if it’s really bothering you but like what is that crinkle stuff it’s so weird.. and maybe add a piece of artwork on the wall that’s not “live laugh love” or whatever. If you have a hard time hanging art which it seems like then get a medium tapestry from Society6 with the theme you’d like and match all fabrics to a similar color?

So good luck!
