#1, bay tobiano colt: Run the other way. While the rest of him isn't really terrible, his front legs make me want to scream. Very long pasterns with a big angle to them. Far too much risk there of a bowed tendon, especially doing high-torque events like penning/sorting.
#2, bay overo colt: Back end is nice, front end...not so much. Upright pasterns, upright shoulder, really short and skinny neck.
#3, bay tobiano filly: No good pictures to judge by, but I don't see anything that stands out as bad.
#4, fewspot appy filly: Very unfortunate looking creature. Fine boned, steep shoulder and croup, high tail set, ewe neck, also looks like she may be calf-kneed on the right front.
#5, palomino (champagne) filly: I like her the very best. Her head is a bit coarse, but that is the only thing I can really pick at with her. Her body is very well balanced for a yearling and her angles are good.
