Thoroughbred mare. trying to learn :)

I'm trying to learn more about conformation and so I figured I'd post my TB mare. We event just for fun and play around at whatever is going on in the area. Any conformation weaknesses that she has I would also be curious as to what would be good exercises for improving on them?
Thanks

The pics are from when she was 14 over the span of about a year. This is the closest I have at the moment of confo pics, sorry about the darkness of the front one and the tail in the rear view and you get to see her lovely color changes from winter (in the indoor) to summer (in the grass) and shedding out in the spring (side view) silly mare :)

She looks like a pretty mare, can't tell much conformation wise unless you stand her up properly, you might find these threads helpful:

Not a bad-looking mare! She's high in the withers, but that's common of TB's. She could do with more muscling in her hindquarters, but she's got a nice deep girth and a good shoulder.
Neck ties in well, and her legs look good.
