Diffraction on lights; contellation manipulation; night photography technique.

Taken recently in Kelowna (http://en.wikipedia.org/wiki/Kelowna). Wondering about the diffraction on the street lights where I deliberately stopped down the lens (14mm (http://www.photozone.de/canon_eos_ff/532-samyang14f28eosff)) to produce this. Also, the time of night has the constellation Ursus Major (http://en.wikipedia.org/wiki/Ursa_Major) rising, and is there in the photo directly up from where the row of promenade lights end, but I am wondering if I should increase the light points to make the image more thematic (constellation/city). Kelowna is named for the bear, and the blue sculpture to the right is a wire frame bear. I am going to re-shoot this image when the conditions are right, but am looking for some input before I head back out again. The first version had the image stretched very wide as there is quite a bit more image on the left of the marina, but here I have cropped it back to a conventional width.
Thanks for the suggestions.

Hard to see in the whole photo so I have added two cropped portions.

The image is a bit small to really give a decent critique I think but those close crops do help at least.

I like the starburst effect and also use a smaller aperture to get this effect at times.

The sky colour looks a bit light (although it looks good too) and I think that aids in hiding the stars. A shorter exposure may have succeeded in darkening the sky and still allowing the stars to shine through ... but only experimenting will tell of course. I see no reason not boost the stars a little to make them stand out a touch more.

That particular stretch looks like it provides a wealth of photo opportunities!
