Most aspects of this are off,
+No safe areas are used
+I would stick to the colour pallet currently used
+Animations are too slow and last for too long in my opinion
+Don't screen-record, export
+What role does Premiere play in this?
I don't want to look like I'm promoting my own mocks but take a look at my MTV mock from this year, look on page 2 (I think) and you can see how I made the graphics step-by-step and which resources I used to help me create my mock/recreations. http://tvforum.uk/thegallery/upcoming-mock-41375/
