Sun has a big, grand, booming voice that is meant to penetrate. Sun is loud and boisterous and show offy. There is nothing he loves more than positive attention and having endless amounts of fun. He is a happy positive person most of the time but can have a very firey temper and can turn quickly into a fit of rage. Sun loves to sing so he can sometimes talk in a sing-song voice when hes very happy.

He is Gay so I don't know if you want to somehow portray that through his voice but its not completely important, only that He can act a bit flamboyant at times (when hes feeling giddy about something).

 I'm not sure if his accent suits posh English or North American, so please convince me whichever you think suits best!
