10.6 iOS app rejection - teasing out the specifics?

Question

Our Augmented Reality app was rejected under 10.6 (I've pasted the full text below). In my understanding from reading a lot of rejection threads elsewhere on the web this can actually cover quite a broad range of rejections, including the explicitly mentioned poor quality UI, apps that could be websites, apps with little functionality, and apps that include graphics assets that apple are not happy about (possibly copyrighted etc). These specifics are usually noted in the latter paragraphs. In our case Im a little confused by them as they dont seem to apply due to the complexity of the app.
Ive attached shots of the app - one while running, the other after hitting the picture button with the sharing options up. The app is predominately aimed at young asian women into nail art culture, and matches our branding in use of typography and colour. The gems on the menu slowly rotate, making a shifting, abstract-looking shape either side of the options.
Is this a straight UI quality issue? Does it look confusing or too low quality visually compared to other apps? Or is it possible the reviewer thought it was just a camera app and didnt get the AR working for some reason (hence the additional iOS functionality comments)? It definitely couldnt be an HTML 5 app, but I do wonder what made the reviewer add that paragraph in particular.
I have sent a message asking for clarification, but things seem slow there at the moment, and I know theres a good chance they wont be willing to talk specifics.
10.6
We found the user interface of your app is not of sufficient quality to be appropriate for the App Store. Apps that provide a poor user experience are not in compliance with the App Store Review Guidelines.
It would be appropriate to incorporate additional iOS functionality within your application.
Please evaluate whether you can make the necessary revisions to improve the user experience of your app.
If you cannot - or choose not to - revise your app to be in compliance with the App Store Review Guidelines, you may wish to build an HTML5 web app instead. You can distribute web apps directly on your web site; the App Store does not accept or distribute web apps.
HTML5 is the major new version of HTML and enables audio and video to play natively in the browser without requiring proprietary plug-ins. <I've cut the rest of this - details on HTML5 apps>

Choose About this Mac from the Apple menu and check the processor.
If it's a Core Duo Mac, you must install the DVD version of iWork. If you previously got a compatible version of Numbers from the Mac App Store, go to its home page and click on Support under Quick Links.
If it's a Core 2 Duo or better Mac, try purchasing Mac OS X 10.8 from the Mac App Store. If you get told that it's incompatible, phone the online Apple Store and order a download code for 10.7.
If upgrading to 10.7 or 10.8 requires any other upgrades or replacements(they both require at least 2GB RAM and don't support PowerPC-only software such as Office 2004), it may be cheaper to buy and install the DVD version of iWork even if your computer can be upgraded to use the Mac App Store version.
