Please Help With The Next Step

This is our back staircase.

These steps lead only to our home gym over the garage.

I want to do some thing really fun with them.
Last summer, I almost had my painter
stencil roman numerals on each step.
We couldn't find any nice looking templates.
 I decided to hold off.

I am so glad we waited.

For many months now,
I have been collecting images of beautiful painted stairs.

Only now I can't make up my mind...
which one should we use? 

1.

2.

3.

4.

5.

6. 

Help!

I have narrowed it down to these six images. 

Which one is your favorite?
