Achieving reflections like that is very very hard, and that was an extremely still night!
There were 2 factors that created the warped star reflections:
• Wind – there was the odd VERY gentle breeze, enough to warp the star but not enough to blur it out of existence
• Wildlife – birds and fish are abundant int hat area, a few ducks landed nearby while it was being shot.
The lans used was a Samyang 24mm ƒ1.4 which has virtually no coma, and is extremely sharp so excellent for astrophotography.
As for the milky way in the reflection, that part of each image was lifted by one stop in Lightroom to get more details.
Here's some better reflection examples:
