I can try to explain in a little more detail what I did, as some are interested

I'm always happy to help with what limited knowledge I do possess!
I set the aperture to f/2.8, which is as wide as I can go on my Tokina 11-16/2.8. I wanted as much light as I could possibly gather with the lens, to get as much detail in the sky as possible. Secondly, I set the shutter time to thirty seconds. There's a two-point balance here, consisting of (1) the amount of light I want and (2) stars starting to "streak" due to a long exposure time. I chose thirty seconds, because I knew, from experience, that this is pretty much as long as I can go before the stars streak too much. You can see a tiny bit of streaking in the shots here, already. Thirty seconds gives me more light than, say, 20 seconds - I wanted to get as much light as possible.
The third thing I needed to decide, was the ISO. I chose ISO-800. Not too much noise, yet I get more detail from the light gathered (to say it like that). ISO-100 would give me "cleaner" shots, but with less detail in the sky.
Lastly, I had my flash. If I didn't use it, the light would be much, much darker (Image 1). I have an old Vivitar flash, on which power settings can't be directly changed. I just tried what it looked like from a certain distance, and just used that for all the shots. Seeing as the shutter speed was thirty seconds, I had plenty of time to move around to get the angle I wanted. In addition to this, I wouldn't really matter if I walked in the frame. I would be very dark, and ghost when I walked. If I stayed in the same place for long, then I might have appeared on the final image as some weird blurry shadow.
As for the angle I used, I chose one that didn't bring too many harsh shadows in the frame, either on the field or on the house itself. I made sure to be in front of the tripod, or else it would cast a shadow.
It's all just basic reflections of how light works in photography

Maybe this helped some!
