Interesting model for the outfits and a nice style. But the real reason i will comment is that posture and expression. Trying to figure out what conversation would lead to those eccentric moves from the guy on the left... Or on the right for us.
Happiness and random joyful moves, a eureka or you got it right expression, a this guy pose and I can keep going. So hard to tell yet the only thing that matters is it seems like one of those moments you immortalize by mistake with a picture. (yes I noticed the description, But letting a mind run wild on it before the answer is better)
