I'm going to consider this render officially done.  Based on an AI image I generated through the Bing Image Generator, I tweaked this scene in P13 until I was satisfied.  Much of the ivy on the mausoleum was generated in the Ivy Generator program, an app that I may be revisiting in the future.  The moon is actually an object with enhanced moonlighting with an area light.  I gave it the PostFX treatment with increased contrast and some glow, in addition to a slight blur affect.
