The mule is pretty nice for a mule; he has a pretty thick neck though.
The QH has a beautiful head and neck and has nice hindquarters and is very balanced. Very nice horse!
The TB is also nice, but thepicture is a little hard to critique. He has a nice head and it seems like he has a pretty good neck. He has a nice deep barrel from being a TB and he also looks pretty correct.
Overall some very nice horses!
