Ok. I'm not an expert on conformation, but I'm trying to learn to make a good critique, so I'll tell you what I see. Her pasterns look a little long to me. She looks to be a tad downhill. I like her head and her color is gorgeous. She's not AS nicely conformed as her brother in my opinion, but she's not horrible.
I don't think her back is THAT long, but she does look a little weak in the back. I like her kind face.
I'd like to see pictures of her movements to give an opinion on how she'll do on barrels.
