Just buy two complete window coverings sets (including rods) the SAME size. One of them will be covering more wall surface than window surface, but so what? No one will know but you.

Also adjust your curtain rod so it's positioned near the ceiling, not right on top of the window.

Not sure what you mean by "balanced". The windows are not symmetric and won't ever be.

I might consider a thicker drape as well.

You want Roman shades, you have no room for the return on the right side of the last window.

I too would go for the roman blinds to help clean up the space.

Spin the bed and side lights to the full wall, mount the TV on the wall.

your bedroom should be an uncluttered serene restful space.

an area rug would add cozy softness and help with acoustics.

Do you need more storage?

Would you still use roman even though they're both completely different sizes? @Sigrid

@Lyn Nielson though the photo doesn't show it, there's a wide closet (with no doors on it). I believe we'll have enough storage space.

regardless of the window size, I would fit the blind to the window, for me... inside mount.

Blinds.com is a great source for affordable blinds and a wide variety of styles, including black out.
