Retaining wall, what to do with the front?

Hey everyone,

I’m slowly building this retaining wall for myself to get a bit of flat ground on our sloping property. It’s one of those jobs where we found the old wrought iron fence before we thought to do the wall and kind of built the wall to suit the fence. The fence was originally bolted to a concrete nib wall so I had to replicate that in timber. I’ve used purple heart which I think looks great, but my question is, do I cover the wall in 140x19mm purple heart decking to match like I’d planned or will it be too much? What could I use instead to tone it down a bit? The whole garden is a work in progress so all suggestions welcome!
