Since I actually took the liberty to make a "Apple OS" looking prototype from the beginning, I didn't change the style because I used observations of my macbook and iPhone to create a similar style.
When letting others test my prototype the first time, I found myself telling people exactly what to do. Unfortunately, I didn't quite accurately, in my opinion, test the prototype correctly. Nonetheless, those trying out my prototype made me aware of the fact that they understood why everything happened how it did when it came to input and results.
Per my own observations, I believe the prototype needs more screens to more smoothly create the transitions occuring in the app. I'd also like to create more "Calendar" shots that could possibly be included to represent the way the new feature addition will add to the app. This includes having a shot that would show exactly how the calendar will look from the iOS app, such as showing the fact that you can scroll through the calendars.
