A Logo is not fashion it is a mark that should be recognized also after a long period of time. Maybe it does not look very creative and very classic and traditional, what I have done here. But it is built on that's what is done before and shows some permanence and simplifies the reference, that looks official

New logo:
There is absolutely no need for, that would be contra-productive to an official image and absolute a bad idea: for the idea of the existing one is good and it is known, new Logo = lost of recognition
Changing and changing and changing a logo, that is not professional

this version is better for it is balanced
It is faster: no frames and no Schnickschnack!
It works in black and white as in colours also in smaller sizes as the existing one.
There is no need for a new CI I think!!!!
