Looks great Jeff!

It's definitely not too dark if you consider photographic principles, perhaps not even dark enough!
In the end it's the artist who decides what he/she likes best!

Wonderful, very much better indeed. If you saved as exr, you could try a HDR version, or a mix, or just raise exposure. For any next render you could raise exposure in TG to 1.5 or 2 or so, and post optimize.
