Awesome image! From a technical standpoint, there is still noticeable noise in the sky though.
I suspect night sky images with stars in them that are being used commercially have been taken with a tracker that rotates at the same speed of the earth. This allows for a much longer exposure, and thus a lower ISO. Super long exposures and trackers come with their own set of challenges though 🙂
The sky still needs some noise reduction. The shadows also need to be lightened up.
Is this your house? Regardless, you will need a property release.
Great image. Congratulations.
The picture is slightly underexposed ( you need to fix this cut-off) and the sky is too noisy.
The art is to denoise without touching the stars.
As @Ralph Lear said, you will need a property release.
