I'm a fan of the clip used the end sequence, although it should end with some sort of focus on Britain. Maybe you could do a sort of reverse version of the 2008 ITV News at Ten sequence, zooming out from the studio building and out to a focus on Britain. This would give the viewer something to look at because at the moment it's quite dull with not much going on. You don't want it to detract too much attention from the end credits but it could do with something more than a very slow pan across northern Europe.
Also, your end credit crawl could do with some pizazzing. At the moment, it's just a generic font at the very bottom of the screen not using much space. The more people you want to credit in the end sequence, the longer it needs to be. There's no need for a 25-second clip if you're only going to credit a few people a la ITV News, or you could even go creditless like the BBC and just have an endboard, with some sort of subtle animation if needs be.
I know I've waffled, but I suppose what I really wanted to say is: You don't need to stick to the regular, generic news sequence. Try something new, branch out! Bring something to the table we haven't seen before. And if somebody calls it crap, keep going with it until it's not crap. There's plenty of generic mocks on here with nothing much interesting, so when something new comes along it's sure to grab our attention. Anybody here could do great things. It's just that you're somebody who's managed to develop that thick skin that, quite frankly you're going to need if you want to head into The Gallery, and are ready to keep pushing to make mocks that can inspire others to do just as great work.
