Hi Andy. I think the very best favour you could do your porch is to stain the concrete to a warmer colour. A container plant at the base of each pillar will soften the edge, and then you can have fun with furnishings. It's a great porch.

The drum is from Pottery Barn.

You might want to consider painting the back wall and the ceiling too.

Ditto what Rina said. A light terra cotta floor stain would be nice. Are those fence posts along the right side of the photo? Is the fence going to be installed? If so, I'd create a flower bed in the narrow space between the porch and the fence.
