I've not seen anyone commenting on social media so far, so I'll have to bring the bad news. IMO, looking at this shark livery, I think of a centralized, military style company, lacking or ignoring commercial marketing professionalism.
If you promote your reliability, integrity, want to make your people happy and committed to what they do, you strive for enduring relationships and partnerships, a bloodthirsty fighter style shark face can not be the outcome.
You might like the art, but that doesn't mean you do market promotion / company branding with it. This is about bonding, not intimidation.
Without knowing, I'm almost sure one or a few probably defense background exec's, pushed this through. And, IMO, it hits all the wrong buttons. Embraer has done a great job over the last 20 yrs, this in my opinion doesn't pay tribute to that. I hope they keep learning & improving.
