He has a nice head and ear, though he is slipped in crown. I'd like to see shorter, heavier bone on him. I do like the length of his body, but he looks to be weak in the shoulders.
Both bucks are pretty similar in type. If you're choosing between them, it would likely come down to how the bodies feel. I'd keep whichever one has the the fuller, wider body.
the pictures aren't that great. the first rabbit is very massive and large boned I don't think you can tell in the picture. he placed before the second one.
