Before critiquing it too hard, the movie clearly had the tone of a lower budget and a lot of fresh talent. So this is always important to keep rolling in the back of your head. It wasn't developed with a big movie budget and big-name stars with years of experience. So, taking that into consideration, I feel it is fair to judge it as an attempt made within its own tier and not against something you'd see from Spielberg.
That being said, I feel that the camera work in this movie was a lot of fun to follow along with. You can tell they put a lot of effort into the shots, as well as in post edit. This was absolutely the best quality of this movie and it did a good job of setting the emotion/mood of each scene. The shots of the open country, the horses/band even the aerial shots were fantastic. The audio was decent as well, with only a few noticeable bloopers. Sounds effects were good as well.
As for the scenes, they absolutely nailed it. The wide-open, with all the right detail to everything. From inside to outdoors, it felt real, and as though it all belonged. Great job on that.
As for the acting, I think I pretty much covered that in the opening disclaimer. I felt that Rinnan Henderson and Mark Bracich did a really good job of making their roles believable. Many others were clearly new and getting their feet wet, which in no way is to discourage them. For most, acting is no easy task in the beginning. You do get the idea that a lot of them had fun getting through it all and hopefully got along with one another (again, it isn't a big movie presence, so I won't go any deeper on this topic as it wouldn't feel fair). The backgrounds did amazing in many of the scenes, from simply riding horses to those participating in crowds.
For what it is, you can tell they put a lot of effort into it all for what they had to work with, and it can be fun trying to find that in the movies you watch.
