Thanks for all the feedback so far everyone! Glad most of you like the BBC Three, Four and Cbeebies identities as I think they are the ones that currently need the most attention from BBC Creative.
I've made some slight changes this morning in another spare hour. I've tried to make them all more consistent with each other by moving the BBC logo to the left on each identity. I have also made the BBC Three text solid now instead of outlined and I've hinted at some branding elements to each identity too.
