Want to redo my bedroom but don’t know what the right move is

Hi! So I made a 3d model of my room and tried to change a few things to see how it would look (moved my bookshelf, added curtains, a chair, a rug, and a few posters). I don't know very much about interior design and wanted to get a bit of insight. Also, the bed that I used is actually a bit smaller than my real bed. Mine would be closer to the end of the window than what is shown here (I have an Awara Japanese Joinery Bamboo bed frame in queen size for reference)

I kind of just put things like the rug and chair in a random place so if anyone has any better ideas for placement and layout please let me know!!
