Thanks for the comments,
I am a total newby at this type of photography so other than aiming my camera straight up for 30 seconds I have no idea what I am doing.
Here is another one we shot a few nights after the one above at the local beach,
and a 1920px version if you want it for a desktop. figuresofstick, this might be better as a desktop due to its orientation. If you would still like the other file I am happy to send it to you, it is quite large though (33mb)http://primalmanagement.com.au/node_1920.jpg
This last one had way to much light damage to be useful but it still looks ok I guess.
