Are there any resources for "themes" that I can use to build an app with? Something like templatemonster? The default black/white just doesn't fit my fancy and I'm not creative enough to design my own. I found http://wp7designtemplates.codeplex.com/ but it isn't quite what i was looking for. I've found a few other sites, some point to the codeplex project and the rest are all the same black and white screens.
The default black/white just doesn't cut it
The Black&White Metro theme do cut it. You should stick to the design-guidelines, and design using the metro design language.
Just because it's black and white, doesn't mean you can't be creative.
Some example screenshots from some of my apps:
Why would you pick another art-style than Metro for things like this? It's all about integrating Metro in your layout. And nobody says you have to stick to black&white, you can also use colours, just stick to a single theme colour (like my first two images, I used a style of pink).
The rest is up to your imagination. UI design / UX comes with practice. And it's a very important part of designing mobile applications.
