I don't like still photos in videos. Attach those separately so I can look at them as long as I need to. If its a photo I'm not interested, then I get impatient waiting for the next part of the video. Some of the stills/photos were taken at the wrong moment, too.
The whole thing seems long. 10min is too much. Cut it down to basic wtc both ways, showing transitions between gaits. Then another few minutes demonstrating special abilities. Also, no slow motion.
One thing about the music, some buyers like to listen to the original sound because they can listen for foot falls and groans and snorting and stuff.
When I make sale ads, it's 2-3 photos: 1 conformation, 1 movement, 1 artistic. Video is short and sweet, showing basics. Minimal editing. Text and is 3 paragraphs: basic stats and description, resume and any training, location price and other misc things.
