I think she is cute. For 20 she looks great, she is a bit of a puff pillow (it seems to be a breed thing, appears most are easy keepers. LOL )
I like her back length, I love that she doesn't significantly lose strength through the loin. Her LS placement is not bad for the breed at all, especially a mare in the breed (for whatever reason ASB mares seem to get a bit further back than the stallions and geldings as a general rule). I like her hip, and general hindquarter build. I like her overall balance.
Her weak points are, she is a bit longer in the cannon than I like to see in any horse, and she is a bit light in bone - neither of those are "fixable"... Her neck shape could be improved by encouraging her to stretch it down and out - like many of her breed the natural neckset on her has encouraged her (probably most of her life) to go with her head in the air, which in turn has created the heavier muscling under her neck, she would likely have a nice neck shape if that were worked on.
