Design Question Follow Up

Earlier this week, I posted this article, asking for your opinion on what I could hang on the walls behind my master bedroom bed.  From everyone's comments, it seemed that it was hard to fully answer my query unless more information about the rest of the room was provided.

The master bedroom is limited because of two major windows, an entrance into our master bath, two very large dressers that need significant space on walls and a hallway (where our closets are located).

Here are a couple of more pictures, as requested:

Very large window on one wall

Asymmetrical window on another wall

One of two very large dressers

Entrance to master en suite

 As mentioned earlier this week, this year we would like to give this room some lift and changes, including: painting grey, updating light fixtures to incorporate more glass and silver, maybe painting out some of the wood, changing knobs of dressers, changing window treatments, adding a throw, etc.

So here are my questions for you:

-What sort of thing(s) could I hang behind the bed?
-What could I put on top of the dressers?  They are really high so not functional for makeup, jewellery, etc. but I would still like to dress them up a bit
- Window treatment ideas?

Thanks!
