?? I see no pavers....just some pieces of lumber.

Do you have something for us to choose from? A paver style as well?

Personally, I would find the switch from concrete walkway to pavers to whatever is surfacing the landing visually distracting for such a small area. Too many materials in too small an area. And your walkway is seriously undersized as well. Either pick concrete to extend from wherever (driveway?) to the landing but at the full width of the step or remove and replace with a complimentary colored paver walkway for the full length and again at the full width of the step.

Anything else will just look cobbled together and niggardly. You want to enhance your entry....not have it detract from what appears to be an attractive home.

Are the paver colour choices those pieces of lumber?
