Please Critique My Horse's Conformation?

[burdfour]

You are right, those are NOT conformation shots , but I will tell you what I think I saw...

The good:
She has a beautiful head and face!
She has a nice long, sloping shoulder.
She has good withers to hold a saddle.
She has good bone, and straight legs, with good angles on hooves and pasterns. Her hocks are set nice and low.

The not so good:
In these pictures, her back looks really long. A long back is weaker, and makes it hard for a horse to collect. (My horse has a long back too)
Her hip and loin look weak.
Her neck is set low.
I would like to see her with more weight and muscle.

She is really pretty, and looks happy and healthy!
