Interesting idea with the +. Not sure yet about the head of phase 1. Perhaps you find something more catchy? That sticker idea sounds nice as well. Not sure though how this could be implemented (doability and costs). Have you done some research on that?
Hm, i'm not really sure that this keyvisual works. It reminds me a bit of healthcare, and especially if you dont work with a striking headline it might be extra confusing.
It is a little hard to understand the keyvisual, but it looks great, though.
I love the colors and good job with all of the material.
Is the last one also a fish? (keyvisual) iF so it is not really clear. But the design is great.
For me the second one is strong. Can you create the visual more similar to a fish. Not much! - only a litte...
Yes, then it gets even better ... and I like the analog interactive billboard.
