not sure if it is possible with your lens but just a suggestion - maybe opening up to a larger aperture may help blur the background more with shallower DOF... but then again if your intention was to get motion blur of people in the background then using a smaller aperture would frce a lower shutter speed capturing more motion... :)
but overall it's a very good shot for the question "What to order?" :)
So were you in the shot facing the camera which was set on timer mode? :)

@Kairospix: Thanks for the suggestion Kairospix. I will try it the next time. I wasn't really paying attention to the background, I was more focused on the two girls! And I was the one taking the picture - I had no tripod with me at the time so I am "not there" in the picture :)
