Nice to see someone trying to create new versions of ITV idents, but i'm sorry these are all quite poor. The footage is very shaky, quite poor quality, and in the last one you can see reflections in the window. The flashing lights one is too intense with fast flashing lights.
I don't think people realise how much work actually goes into making the ITV idents, its not just a case of grabbing a camera and filming any old random stuff they can find. If you actually watch them properly, they are filmed carefully, slowly, and focus only on certain aspects in each shot.
Try making a new one, find somewhere you can take your time to film, somewhere where no one is going to bother you, get in your way etc, film slowly, and maybe do the same or similar shot several times so you can pick the best version.
I hope you do take this further, I would love to see you take time and improve your mock, please don't let my comments put you off as that is not what I am intending. Good luck
