Maria :)

I don't know... Not really... 

Je pense qu'ils ont tous quelque chose de positive. Guillaume est unique en son genre. J'aime la folie et l'innocence de Frédéric et la simplicité et la voix de Casanova. 

(sorry I don't know how say it in English) 

I understand you @Maria :) I just think who has the biggest chance to make a career after all. Casanova sings very well but he's ordinary, Frédéric... well Frederic is very specific  and Guillaume is also not that obvious choice because you can like him straight away or not but he's the one who is different than the rest 

Casanova; because he's cute and tall.
 Apparently it's a mixture that works well with crowds.
