When I first opened the site there the main graphic loaded really slowly. Its a 2.1 MB PNG; you may want to change it to JPEG since it'll be way smaller and look just the same (especially since its a photo to begin with).

Edit: I made a 60% JPEG from this PNG that weighs in at 281KB if you want to use it:

Also somewhat weird that "Get this app" isn't centered like the rest of the content.
