Hi Dee Dee,
For your liberty shots, if you could have someone lead a mare around outside(further away), you will get quite the expressions on your stallions.
My little mustang filly is quite the tease, already at a year old, so when I have an extra hand, I'll know to use her for any of the "boys" shots..or...typically, take them from who they are used to hanging with, and that'll do it as well!~
Good luck on the early am shots!!
