Better pictures would definitely make it easier to evaluate this heifer. One thing in particular that bothers me is you cannot see her head in the pictures and that to me is a very important part of evaluating a female.
She does however look to be quite stout and square made, all 4 legs square under herself and she looks like she is quite capacious and deep ribbed. In these pictures she does look like she may be a bit coarser made and perhaps a tick "Staggy" but I'm pretty sure that these pictures don't do her justice.
Overall I bet she is a pretty darn good heifer.
