Photo's in the park at night

I took these photo's last saturday night over at Victoria Park in Glebe, just before heading over to Bar Broadway. I tried to go for something a bit more interesting this time. I made it so that the shutter would stay open for longer than necessary. i wanted to have the blur of the traffic in the background of the shot.

These kind of shots are only useful at night, as there is too much light in the day. Oh yeah, i should also mention that keeping your camera steady in a shot like this can be extremely difficult when you don't yet have a tripod. But hey they don't look too badly blurred. What do you think?
