It would look better if it didn't have the white background. It looks very unfitting next to the other 3 icons.
Really, none of the icons flow. You have Photos and Game Center with their simplistic blob design, then you have Stocks and Compass being almost completely black, then you have iTunes, App Stores, Music, etc. with simple gradients, then you have Settings which is just a total mess. I find it hard to believe that this is the best that Jony could come up with.
Other than the Music app, I think they all look great. It doesn't throw off any more than the current icons do. The only issue I have is that the Music app just is a shade of red/orange that I don't like.
To be honest, I hate those icons, and a couple of app interfaces, but on the whole I like it!
I hate that safari icon though!
And I wish they could've brought some form of animation, such as having the gears ocassionaly spin when an update was available, have the weather app change colour depending on the weather, that sorta thing! Oh well always ios 8
I think people are forgetting that modern [graphic and UI] design is headed toward flat designs and minimalism. The older icons looked more polished because they have a ton of skeumorphism and all kinds of glossy effects added to make them look like bubbles. In 2007 when the iPhone was first released, design was full of gloss and drop shadows and complex things, now, it simply isn't. This is Apple keeping up with the times and trends of design, and I welcome it. iOS is getting very stale and looks nearly identical to how it did in 2007. Stop being afraid of change, Apple would eventually lose a lot of customers(myself included) if they didn't update the UI in a significant way.
