Yep, you're better at a canter than I was when I started.

The best visualization trick I've found to sitting the canter is to think that your pelvis is an ice-cream scoop, and you are rhythmically scooping out ice-cream with it, bottom (seat bones) leading the motion as the horse's back goes down under your seat. 

You were posting on the correct diagonal as well as the proper lead at the canter.  I noticed that you got your canter when you stabilized your inner lower leg at the girth, gripping with your upper calf.  Nice.

You know, this horse really might be a very good schoolmaster for you.  Listen to him with respect.  He will teach you more than any human.

Thanks guys!

The stirr-ups were to long so keeping my heels down was more of a chore than it usually is...

this is not to be rude, but both in english and western you can be doing more both for you and the horse. You look to me like your going along for the ride, and not actually riding. Your stirrups being too long IMO should help with a seat,in both english and western your heels need to be down, and I prefer the iron to be on the ball of the foot, not in the middle. Big security thing for me. Holding onto the horn actually does the opposite of what you want it too, holding to the horn makes you go forward not stay back. The "air" between you and the saddle at the canter concerns me since the western horse looks very comfortable. I would talk to your coach about more stirrup-less work and sitting work to become more subtle with your cues, and more comfortable for yourself and the horse, AKA a better seat. I'd like to see the horses riding more collected unstead of hollow, which means leg, and a steady hand to round the back, not a headset. Also more thought into asking for your cues will make it look more put-together. I wouldn't be jumping until all of that is mastered. Even some side pass, and flexion, riding in the square, and serpintines will help both horses and you. The english horse seems a bit bracey to me, ears back very uncomfortable but being a good boy, and this is where I think your seat needs work, and the horse is riding hollow by his neck which has more prominant muscling giving him the look of an ewe neck. Also do not hold onto the horn, hold onto the reins like you would in english, or one handed, the postion of your hands is unactive, and if there had been any type of bolt/spook/buck etc you do ont have active hands to correct it.

the reason I 'picked" on you in english unstead of western is the western was your first time.

I used to be A_Sassy_Temptation on here, I posted alot on the western forum, then I left for a bit, and now my account doesn't exist. So unfortunatly starting from scratch or I'd show you some other threads.

However Emiry, both those horses look like great horses to work with
