Very nice work.. thank you for sharing!

It looks like some of the extensions you are using are not responsive however some fixes maybe be applied by using the Custom CSS fields in the 'Responsive Options' tab of your templates parameters.

An example would be something like the following in the 'Mobile Landscape' field for your twitter module..

#jmod-container {

    width: 350px;

}

The same again can be added to the 'Mobile Portrait' field with a smaller width...

#jmod-container {

    width: 200px;

}
