My boys did not do well in showmanship their first few years, they did well showing in market but never stood out in showmanship. Fast forward to their last few years, and about 8 years and 40 shows later, it just became natural; they showed the same in market as they did in showmanship. My youngest won senior twice, the oldest was in the top 7 out of 30 the last 3 years (the 4 girls that were always at the top, those three years were flat out good, with a calf, hog or lamb, watched some epic battles when it came down to those 4).
The extra shows helped them understand what they needed to do in different situations, they did not need to think about ring position, setting up the animal, loining them and grooming the steers after the judge got his hands on them but after he has finished with your animal. These things were what tripped them up early on.
The biggest thing was working with the animal at home, getting them to step into setting up instead of having to adjust their feet all the time, and learning good is fine, they do not have to be perfect. The more you mess with them the more ornery they get. Watching and learning the animal's strength and weaknesses, determining the right speed your animal needs to be at when walking to look their best, setting them up to hide their faults and expose their strengths. The more they work with the animal at home and the more confidence they have in themselves and the animal the better they will do in market and showmanship classes. To me they need to be confident, look comfortable (not uptight or nervous) attentive and be aware of their animal and judge at all times, the rest should just flow from the work they put in at home.
Every year (or show) if she learns something new, enjoys herself, then it is all good. Overtime all those little things she learns compile into a confident show person.
She will get it as she grows more comfortable and certain of herself.
