learning to use long exposures ya ? .. =)
nice effort. Sharp..glad that you got yourself a tripod. Nice stardust effect.
alright here's how I see it ..
Long exposures are fun to day, we see traffic trails ...however besides that your photo also needs to have a "primary" subject. The primary "subject" has to be something interesting and catches the viewers attention the moment he/she looks at it. In your case, the wow factor seems to be the biggest light burst. Which is alright but it lacks the "interesting" factor.
What you may do at that point to make a montonous subjects interesting could be to find a frame for it, or having a contrasting secondary subject in relation to it.
It maybe difficult sometimes because nothing arounds you make interest you at that point of time. That's when you can stick to the basic guidelines e.g rules of a third, framing, lines and patterns, other refreshing angle ( e.g top down or bottoms up ), colors or differential focusing.
There's nothing wrong with your photo but there's nothing "wow" abt it either. Sticking to some basic fundementals may draw more interest.
my crappy two cents worth of comments .. =(
