I like the concept of the blocks background, but I think it may look a bit distracting with the BBC letters in tact with the boxes. Maybe having the boxes without the characters could work better and less distracting.
Other than that, I quite like what you've done with the CBBC logo which sort of breaks the BBC guidelines but at least it attempts to do something creative than being limited to being flat blocks.
This is a very big step from what we originally saw at the start of this thread. I hope you continue with ECPs
, develop more on promo graphics and maybe consider doing News/Parliament logos/graphics next?
Do you even read these?
