I can't decide!

I just painted my bathroom today. I've drawn a sketch of it below. The oval is the toilet, the rectangle is a shelf thing.




I can't decide what I should put on the wall behind it, if anything.

I"m leaning more towards the first two than the last one.

I know they all look way too big, but they all fit in the open blue space.


What do you think?
