Quick advice on Revealing Module structure.

I'm fairly new to JS coding outside of little functions that use jQuery, but I am fairly aware of patterns and practices. I would appreciate some input on my approach so far. Inside my main (revealing) module, I would like to have objects that expose all their methods for use inside the main module, like my commands object, but then I would like to expose a limited set of commands for clients of the main module. I am currently looking at this:

var rotatingBannerController = (function() {
    "use strict";

    var imageList = (function() {
        var buffer = new CBuffer();
        return {
            rotate: function() { buffer.rotateLeft(); }
        }
    })();

    var privateInit = function() {
        // Do init stuff like load list and config.
    };

    var commands = (function() {
        return {
            rotate: function() { imageList.rotate(); },
            init: privateInit
        }
    })();

    return {
        config: config,
        commands: { init: commands.init }
    }

})();

The reason for the commands object is to encapsulate my commands neatly for use within the module.

I am deliberately avoiding more advanced topics such as conctructors and prototypes here, until I establish a working module. I will then maybe upgrade the module to a fully fledged Object.
