im not critisizing here, just trying to help :)
Don't post pics of your 'carefree' rides, or don't have them, everytime you ride pay attentiong to your position and soon it will come naturally and then every ride wil be a 'carefree' ride, then you wont ever have to pay attention to your whole position, sure maybe a few things, but not stuff like if you head is down and a hundred other things.
Also, if your asking if your horse will do well in dressage don't post pics of your 'carefree' rides, you can't expect people to judge your horse when he's not at his best just because you don't do your best. Taking a picture of her trotting/cantering free in the feild would be better, you may not realize it but when you get on your horses back and don't try to stay balanced and in the right place you are actually making your horse look and move worse then on his own. :)
If there are no horses in heaven... im not going.
