I've been stalking your youtube channel and I definitely am noticing a pattern of not enough bend on the barrel pattern, not just on Squiggy but on your other horses as well. I hope you don't think I'm being too nitpicky on you, but I think it would help you out to check out the horses I filmed from my own barn. This is the lesson I watch all the time, and recently have gotten the ability to ride in that has helped me a lot. It shows a lot of the manipulation and bend in most of these horses, and there's a good amount of two very serious girls who pro rodeo and then two who are just out there to play.
You can see here exactly what I mean by the inside leg too...I hope this can explain it better than I did, particularly at 1:45 with the grey mare.
And then a private lesson with Cindy and her palomino gelding. I should make a note they found an issue with this horse's bridle after the lesson and that is why you can see bracing and resistance with him in this video, but there's a couple places where you can get the point.
