Note: All based on version 2 of your work
I like some of the stuff you've done here, but to me it's nothing compared to David Lowe's original. That's mainly because I think it's the best musical theme on TV at the moment (and has been for the past 7 years). Sorry, it's nothing personal.
The bass synth kicks arse though, and I like your strings
The beeping doesn't work as well, although I'm glad you got rid of the "middle beep" from the first version (totally wrong in my opinion

). I don't really like the way it changes pitch halfway through a bar.
I think in the original, Lowe's emphasism was on the beat, the beep and the drums. That said, the drums are the focus for most of his news themes (He did Norway's TV2 News theme and that also features extreme "drumming"

)
Here are some audio files for reference. They are the most recent versions of the themes available at the moment.
Unfortunately, they're all as .wm(g)a(y) files because I can't be arsed to convert them.

The intro just explodes....or my headphones are too loud....but it still rocks...in an electronic sort of way.
