Mike Rundle says iOS 7 Went Too Far In The Other Direction
People weren’t happy with the over-indulgent skeuomorphism in iOS and and now people still aren’t happy.
I’m with John Gruber that the skeuomorphic training wheels needed to come off, iOS 7 looks beautiful.
If you create anything—music, art, writing, computers, whatever—listen to criticism (if you want, good criticism does exist), but trust your gut and do what you think is best.
Like Andy Warhol says:

Don’t think about making art, just get it done. Let everyone else decide if it’s good or bad, whether they love it or hate it. While they are deciding, make even more art.
Remember, Rolling Stone magazine trashed Led Zeppelin’s first album when it came out.
Screw what people think.
