Very pretty and nice horse!!
The first thing I see is that you need to push her deeper in the turns. Especially in the first video second barrel, you are WAY too tight. She loses all her speed. So give her more room around all the barrels. Do NOT start asking her to turn, until her flank is at the barrel. THEN ask her.
And watch your third barrel. You came out wide on the second video and I suspect it's because she's turning too soon. Make sure you FINISH your barrel turn and keep those straight lines.
The other thing I see, that some people may disagree on, is I feel you are making too big of an arc coming into that first barrel (more easily seen on your first video). The more ground you have to cover, the more time the clock eats up. I'd start your run just a tad more to your right, so you have more of a straight-ish approach to that first barrel.
It's fun to goof around with your horse, but I would not be goofing around with her on barrels. You practice that pattern wrong ONCE, and they can pick up back habits from it. Next time, do some reining brideless or something, without the barrels. You're working so hard to make a good barrel horse, so it's not a good idea to let her think its okay to do the pattern sloppy.
Otherwise, she's really coming along nice. Just push her deeper before you turn!!
