It is, but therein lies the problem.
First off, we need to understand that the moon is a very bright object in the sky. Even though the sky may be dark, we need to remember that its source of illumination is still the sun. Sunny 16 applies, if you want to correctly expose the moon.
In these images though, we have the landscape components, which are not being illuminated by the sun. I suspect the light painting or a handheld strobe might not quite be up to the mark either, and thus a decision needs to be taken as to just where the choice for acceptable exposure lies.
HDR may be an appropriate course of action here.
btw, I like the second of these; that is a very pleasing composition for me.
