I'm confused about HS being taken seriously as an artist cos I see that he is in various music publications (FWIW) and I don't know if this is a 'serious' opinion about him or if he's got a very persuasive PR team.
His voice doesn't seem particularly interesting. The way he dresses is the most interesting thing about him. (Notionally, at least.
Saying that I do find that 'as it was' song very catchy. Pop stars at his level have access to some very talented producers/musicians/songwriters, after all.
