Not bad. You have the basis for a good video there.
Your cinematography is good and I am impressed by your musical talent. What it needs is a framework of a story to hang it on and a purpose for that music.
Filmmaking is a form of storytelling and watching the video on the Odyssey it was never clear what story you were telling. Was it the story of the ship? Of her sinking to become a marine park? Of your journey to her? To borrow a line from The Hurricaine Riders, a kayak group out of Canada, "Turns out making real films is harder than we thought, so instead here is three minutes of surfing and a sick track". That can work, but it's not the most satisfying.
As for the music, it was good, but it didn't seem to be setting the tone. Music is how we, as filmmakers, tell the audience what they are supposed to be feeling about what they are watching. Is this supposed to be scary? Adventurous? Triumphant? How should they feel about the story they are being told?
Below is a video I did very early in my career about how music sets the feel of a video.
Finally, your text descriptions took up a lot of the screen and the viewer's attention from the footage. I know narration is hard, and honestly scary, but in this case I think narrarating rather than printing on screen would have made for a better end product.
I think you are off to a good start and by thinking about your storytelling from the viewer's perspective a little more you can make some awesome videos.
