Following the karaoke comment in my feedback, and addressing this in my annotation, I have decided to go back over my storyboards and include annotations on them.
Instead of doing this straight on the sheets (this seemed like a good idea at the time), I decided to scan in the storyboards and print them out to annotate instead, which explains the lovely shade of grey they now are. I also used a different colour for it so that it will stand out more.
Just looking over the storyboards now they have annotations on them they look more interesting and engaging, which is what I should have done originally. The ideas are now a lot clearer and the intended movements are well mapped out and explained. Good move.
