How to model a "Bas Relief" in Rhino?

Hey there,

I would like to recreate something like the object seen in the picture below.
Is this something you would even do in Rhino or would it be better to look for an alternative to create models like these (possibly Blender?). I have looked on the forum, youtube and the web but could not find a resource that would point me into the direction of creating a relief like this.
Is this something one would do with the new subD Tools in Rhino?

If anyone has some resource or idea how I would best go about doing this, I would appreciate it.

Thanks in advance!

Hello - SubD surfaces would be the tool to use here -
