incredible small tugboat, worked hard on the river, stour, waterway, boat, 

I love, love, love the old school instrumental music!

Love anything from the rivers and canals of the UK! If I might suggest, lose the music, and add in the ambient sound. what you would hear if you were standing next to the videographer. Also, maybe try to brighten up the images. Silhouette shots are useful, but should not predominate. Keep it up!
