It's hard to review this design if it is supposed to be for the iPhone - the minimum resolution of the website URL you gave is 910x560 - way too high for the Iphone's 320x480 half VGA resolution.
Also, you chose icons that are extremely detailed - when you size down icons as intricate as these, they tend to look blurry... icons for low resolutions need to be designed with the exact target size in mind, you cannot just take a bigger icon and make it smaller. Same goes for the serif font you use for the quotation.
uhm you speak about resolution but the screen is take automatically from concept feedback with a normal resolution, not witha phone. With an iPhone i see correctly the size and small icon.
For the big icon i agree with you, i'm working to optimize them. Thanks for the review!
