Hey Sharon! I think that if you practice like your showing that can help! Also working your hardest and spending time working with/watching professionals and your trainers riding your horse! Also, reading some judging books really helped me!
An example: You be the Judge by: Randy G Roy also watching Taylor St Jacques!
Hope this helps:))
Walk In the arena like you own the place and no matter what mistakes are made, your confidence is never lost. A real personality is never forgotten.
Don’t get distracted just focus on what you learned
