You both look good together and you look like a nice quiet rider. You could be asking a bit more from your horse, e.g. Asking for a bit more inside bend. It was hard to see your heels but what I did see didn't seem like they were sitting too high, I would work on your rein contact. Your hands sit quite low and your reins are a tad too long so I would carry your hands a bit more and shorten your reins a bit.
Overall she looks to have nice rhythm, a bit rushed in some places and the downwards transitions from canter to trot are what I would work on too.
This should improve if you adjust your hands and reins as described above, but also just prepare for the downwards transition a bit more. Giving your horse a half halt, keep the lower leg on and sit up a bit more.
