I wish she hadn't had her housecoat and curlers on, so to speak, when I took that picture. (We had also just been through three run-throughs of the Novice "C" dressage test and a jumping course, so she was absolutely pooped and it shows.) When I get her in frame in a nice extended trot she looks more "together", especially her back. (Hey, I'm sensitive about "broodmare droop" myself!) :-D
Here's a nice head study. She does have a classic T'bred head. (Even if her mouth is full of hay and she's in the process of taking a good big chomp.)
I don't see any such droop on her! - She's beautiful!
