brightly lit building v.s dark, dark night

78 sec, ƒ /16, ISO 800, 130 mm; 62 sec, ƒ /16, ISO 200; same RAW image reduced by 3 stops in Samsung RAW converter.
I'd been meaning to take photos of this scene at night for a while now, and finally got round to it. "Correctly" exposed it had no detail on the cornice of the mausoleum, the trees behind were barely visible and the church tower was also lacking its delicate metalwork. HDR programs I tried using didn't seem to understand what I wanted, they turned it into a horrific mess of light and noise. So I sent the day painting in and out layer masks in GIMP to get the details without too much noise.
I'm fairly happy with how it turned out considering I'm pretty new to photography, processing, HDR, etc. I'm sure there are a million things I could do to improve it though. I'd love to hear any you can think of and any other comments on subject, composition, WB, etc. And did I miss a trick with the HDR software? I tied Luminance HDR and FDRtool.
Many thanks, Becky
