My digital document

So I've been working on ym digital document a lot, but I'm definitely not done yet. There are some things I've really been struggling with like making it long enough, having enoughpictures, making my music fit and flow, and really communicating what it is I'm learning. I'm very nervous about trying to do the narrative and make it fit with my story and make my whole document cohesive. I don't have any videos, either and I feel like they wouldn't fit in my story that well. I need to do some more work on my project and I'm just feeling like I don't know where to go next, like do the music more, or get more pictures, or try to do the narration, which I thought I should do last.
