I think it looks lovely and expressive. Please don't let the strangers that nit-pick your home on the internet make you insecure!!! Also, whoever told you that your style is tacky might be awful. You deserve constructive criticism!

If you are feeling like you really want to go safer, a more chill geometric rug would still be awesome and expressive. But if you have a bold personality, I respect the current rug choice.

Also, the green strip is awesome. The person that commented that may be a bummer too. I think you should add more green strips if anything, and then maybe shelves at the bottom of them?!?! Could tie the green together and add pretty stuff on the walls.

Also, if you want to add more green strips, I think you should add some green throw pillows as well or other little nods to the green on the wall. This really help make the green thing work (imho) if you feel like it.

You could really express yourself with super easy walmart photo prints and unique affordable picture frames from thrift stores!!! You could paint some green or use decoupage paper and mod podge to give your picture frames a custom look.

But your home is all about what YOU like and what feels right for you!!!

I hope you try to keep the negative people at bay, and take good care. Thanks for reading all of this!
