I just installed both mods, and first I've got to thank you guys a lot for the easy-made installation instead of copying tons of files to some obscure folders.
The BM graphics sure have a much darker tone, a bit too dark for me. But it adds a very "organic", realistic touch to the surface.
I like the looks of the graphics the most when I'm playing in "Civ 1 perspective" (anyone using this as often as I do, especially when your Civ has grown big?), that is upside down just before the game switches to a "just look, don't play" mode.
In this perspective the planet looks plain realistic, wow!
The overall darker tone has also the positive side effect that the border of Civs are much more distinguishable now, with some sort of "neon glow". Nice!
The scaling tool is quite some fun. The units size was waaay too huge for me. Now my little folks have to wander around a huge planet, which again adds a lot to the realism. And if I want to see what's going on I may still zoom in.
I also have the impression as if this graphics mod speeds up the game. Those lags I experienced before are gone now. My, I won't mind.
