Thoroughbred body types

I'm learning a lot while working on my thoroughbred filly. One of those things is how varied the body types are even within horses of the same grading, age, and sex. I made this little animation of 4 year old G1 fillies to hopefully show what I mean (click to start):

I picked these 5 fillies as they are very different from each other but are all 4 year olds and rated G1, the best of the best. If you look at one body part at a time the differences start to jump out at you. Necks...shoulders...legs...overall balance, etc. Of course the one vital part you can't see in the photos is the heart, the mystical properties of which can be poured into a less than perfect body resulting in a consistent winner. Interesting, isn't it?
