I don't know, Hanno looks like he's kinda douchey, here. WAAYYY to confident-appearing to me. He seems to me like he might be a bit on the conceited side. Not trying to be judgmental, but that's the impression I've gotten from this and other instances. I like Max's personality better. Max comes across as unpretentious and relatable. Hanno just seems like he likes himself too much. For good reason, though.
Now I have to stand up for Hanno.
I know what you mean, he seems very confident. But I think Hanno is just very spontaneous and open. He doesn't "feel" arrogant or conceived to me.
And he looks a little douchey at this picture, but I must say...I love it. And that smile. He is shining. Maybe that's why I think he is just enthusiastic.
