Ditto to DrumRunner.
I would completely take your horse off of barrels for a while, and work on the maneuvars DrumRunner mentioned. I'm actually doing the same with my barrel prospect right now. No barrels until I can control each and every part of his body, at all times and at all gaits. Sidepassing, diagonals, rollbacks, turns on the fore, lead changes, breaking at the poll, arcs and counter-arcs, etc.
We've given you this same advice in your other post Critique My Run !
When you get back to pattern work, AFTER you've worked on general training with her, you need to SLOW the pattern down. You don't realize the bad habits you are creating with her right now. Bad habits are very hard to fix. Go back down to trotting until you can do everything perfect: Your hands, your body, her collecting and rounding around the barrels, perfect straight lines from barrel to barrel (no arches), etc.
Your horse has potential and although I know you want to see results right now and figure the problems will just go away if you keep going at it, you need to back off, slow down, and fix things. I can say this because I used to think the same thing at one point in time. But it doesn't work. You have to do things SLOW and correct.
