others may have a different view. But the focus on Dreemport is the written word. For me that means any picture/video/audio has to be secondary to the written portion of the submission.
For yours the video is the key portion of the submission. You could post the video on 3speak with no written content and it stands by itself. If you took the video out of the submission, it doesn't hold.
As I said, the written part of the submission is more in line with what's looked for, but for me I think you need dwell on the guidelines (below), and possibly check out what others may think in the Discord
please do not take this as a diminution of the fine work in your video! I'm just not sure that a post focused on the video of you producing a fine recording meets the required emphasis on written language.
