critique the horses? :-)

These are my own personal horses, and I just want some opinions

The top is a 13 year old mare heavy in foal, recently purchased and never had her feet done. We are working on training her to pick up her feet for the farrier.
The second is a coming 2 year old filly
3rd is my coming 6 year old mare
And last is a 13 year old mare also heavy in foal.
