As for the noise, I was on ISO 400 after all, but I don't notice too much noise; I actually like the little bit of visible noise
When you say "one of the two" I assume you refer to foreground/background? Or do you mean one of the two images. If it's foreground/background, then I'd like to point out that if I'm gonna blow a grand on a camera for a hobby, then I'll take advantage of every bit of RAW data available
