I'm a bit surprised at the number of positive responses that this has received, but perhaps that because I am not quite understanding what your project is about.
From what I am understanding, you're creating a set of idents for ITV to either replace the current set (ITV Creates) or to try and recreate them? Please do correct me if I am wrong.
I have to ask myself, "could I see this on television?" and the answer, in this case, would be "no". It looks to me more as if the type of thing you have created may have been an example played to ITV to sell them the concept of ITV creases, rather than as a finished product, a bit like a moving mood board.
There is no doubt that it looks pretty challenging to have created what you have and I know that I wouldn't even know where to start if I was trying to recreate it but while it is tough, from my point of view reminds me of a more advanced (moving) version of something created in Google Sketchup.
I may be completely missing what you are aiming for with this design and therefore viewing it from the wrong perspective but I don't really think this is good enough to be shown on television or as good as the ITV Creates idents we have to date and so can therefore only give it a 3/5 at best.
As I said, please do correct me if I am missing what you are aiming for with this project
