Newly cast concrete wall - what are the possibilities?

[shine76]

A week ago, I poured a concrete wall around the back of the property. The color is nice, but the surface has an industrial look that doesn't match the house very well. Today, there are holes for the supports, air bubbles, and lines from where the joints between the boards were. What are the possibilities?

Some I can think of: Lay frost-resistant tiles, paint, plaster, sand (although it's probably hard work on a wall), accept, plant climbing plants.
