Deep cleaning HELP

So since we currently live with my husbands family, I have a lot of things in my room that usually don’t belong here but because of space I need to keep em here... the thing is that as I hard as I try to make everything look nicer I’m still not happy and feel like i can do many more things , also two of the furniture is not ours is his parents and full of things and I already told my husband many times to do something with it but nope so I guess it’s not an option for now ....

-my closet is already full of things

Any tips or storage things you guys use that would help I would appreciate it!!!

I love organization and all that but unfortunately right now I can’t do much

Here is a part of my bedroom and I hate it specially when watching tv

And the room is pretty small too

Btw next to the TV I have my makeup and on another furniture I have more makeup and my brushes
