Welcome to IIS Dean and what a great first post.
Not sure I can offer any tips for improvement. You shutter speed looks to have been very good with no sign of major star movement. Focus is great and you have picked up some nice detail in the foreground. White Balance of the stars is really a personal choice. Initially I thought it was a bit too 'cool' to my taste, but then I noticed that it looks like the blue lights from that sculpture(?) are shooting up into the sky and blending with the colour of the Milky Way. What ever lens you are using shows very good optical qualities with minimal coma of the stars at the edges. Any chance of sharing camera/lens details?
You certainly have all the basics (and more) nailed down. Now it's just a mater of finding more good locations to pair up with the beauty of the night sky. Clear skies and happy shooting.
Cheers
Greg
