I really like her hip/ back end, she seems to have nice amount of bone and her canons/ pasterns are both nice lengths. Her shoulder looks pretty steep to me, and she is slightly sickle-hocked, her back may be a bit long and her pasterns are very upright. In the last picture she looks like she may toe in a bit. Overall, she is a nice mare, except for her steep shoulder and pastern angles. Don't forget to start a foaling thread!
Also, these aren't the best pictures for a critique and I'm an amateur, so take what I say with a grain of salt, haha.
