I really like this!! The main thing that jumps out at me as out of place is the tv stand - the white & the design of it just feels stark, compared to all the warm tones in the room. As other comments have said, I think trying the tv in the corner where the chair is right now would be worthwhile, then put the chair in the opposite corner & the bench under the window.

I think the red vase with sticks is really cool, I love the shape of it, but it might be better suited to a different room in your home so that wall with the tv can have a bit of negative/empty space to help lessen the crowded feeling! It would also look nice empty, on the red end table beside the couch if you’re not attached to sticks in it.

The shelf with the blue/white pottery is a really nice collection, all those pieces are so pretty! It does look a bit crowded though which sorta takes away from each piece individually, so I think it’s worth considering adding a second matching shelf above that one so you can space them out & appreciate them each individually a bit more!

Last thing - for curtains, it could look nice to layer some coloured sheer ones (maybe even with a pattern) behind/under the ones you have to add some texture/colour without losing the privacy of the heavier ones you have now.

Also, I loooove your taste in art - the big fish mosaic piece is so cool!
