The video worked for me! Your leg position looks good and overall you seem to be moving with her well! Your arms seemed a little tense to me and seemed to scrunch up at times. Other than that, the only thing I saw was possibly your upper body tipped a little too forward at the canter. Nice work! Does Squiggy usually bring her head up every now and then? I saw her swing it up a few times.
A horse is the projection of peoples' views about themselves--strong, powerful, beautiful--and it has the capability of giving us escape from our mundane existance.
