Hollywood made actually a good copy of cowboys who lives really a long time ago. But they missed some details. it not really noticable but to know more you can ealise that everything is not so perfect.
The first thing fell into my eyes are shoes. Actually cowboys had high heeled high boots with pointed toes. The reason of all that details is the most important thing for  the cowboys- cloth must be comfortable.
High heels made them feel safety because it worked like anchore. High boots were to protect the ankle and foot. And in video his boots are really tiny.
Other important thing for cowboys was their horse. It`s like friend for them who can help at all different situations. In the video there is no horse. Both of cowboys just walked on feet.
Finally, Hollywood showed us a real cowboy but they lose a lot of important details.
