Below is an thorough list of terminology which must be used when talking about the micro-elements, because the Media Language you use was the language of cinema and the moving image (for your openings and music video) which is all to with the combination of camerawork, sound, mise-en-scene and editing.
Other things useful to mention would be how you used signs and codes to create meaning so talk about the denotation and connotation of the images you created.
Media Language has been described as a 'catch all' concept, so feel free to use any of the other theories you've learned for the other sections to help you explain why your project works and how it creates meaning for the audience.
