I enjoy them!
I enjoy open tourneys that are run well. That is hard. If the promoter is good he can usually eliminate bias from his judges by making sure there are five for all events and not more than two from the same school.
As for your daughter, most of what I see from kids that age is a lack of circualr movement. They like to move straight in. Plus, they tend to not keep their hands up. Also, they make one strike and stop and look at the center judge instead of combinations. Also, most areas don't allow face contact for the kids...doesn't mean it won't happen though.
I would work on the areas mentioned above, as well as learning not to jump when someone stomps their foot.
With respect,
