Unless you will use it for reflecting something nice or just dressing, then I would hang some art. What else is in the room?

I see that you have a mirror over dresser and IMO the floor mirrors are overrated. Still recommend art. Bedrooms are a perfect place to hang family photos or more personal pictures. Try a series of framed photos. Maybe even pictures of your view.

If you put an oversized mirror against the wall, then you'll have four, somewhat massive shapes/rectangles in that corner: closet doors, mirror, door, dresser/tv. I would add one large or three smaller pieces of art. Here's some ideas:

I like mirror there. but instead of plain one maybe something with frosting on it - similar to http://sainteriordesignstoronto.com/dream.html

another option you can use shelves like - http://sainteriordesignstoronto.com/dream.html

People walking by would catch on mirrors and baskets?

Do you like your tree art? if so, maybe a very shallow-depth wood shelf to place under?

Beige or ivory? with throw / yellow shams? what's currently your headboard, etc.....?

I like your olive one since its earthy tone draws out earthy tone of wood. The solid seems to draw more attention over to detail in dresser.

Not that this is large enough to place diagonally over your bed, but an option for color:

What color are your walls?

White sheets with everything.

I am not a mirror fan. In this case however, if a mirror would reflect the lake view, that's what I'd do. You'd have to hang it, not lean it, and it should be portrait orientation (not landscape). Would the mirror you removed from the dresser work?

Another reason to like the olive rug is the nature setting of your photo, lovely... :)

Golden yellow and green are good together. But what colors do you like?

Maybe something that matches the dresser:
