I used multiple exposures for the foreground in the same fashion that a real estate photographer would when popping flashes on the outside of a house. I put a CTO balloon, (at least one that provides the color close enough to what i want), over my flash and just started popping while my intervalometer was taking multiple images. I ended up only using two foreground images. I got one flash pop nicely on the rocks and another on the tree. The Milky Way was tracked.
I'm on the fence of whether it's too saturated or bright. CC welcome.
