Don't loose the kitty!
I will have to say that Lumo 2.0 is a huge improvement from what I've tried so far. But previously one of my favorite things was the cat avatar and in general the overall Lumo branding which I think has been spot on.
The new amorphous gradient blob background really screams "I'm an evil AI company and will happily Skynet everything you love" and seems like a real step backwards branding-wise.
