Personally, I'd like to see a smidge more weight on her. Weight turns into muscle so if she starts down the muscle building path without enough weight, she's going to have a hard time muscling up. I think probably 20lbs, maybe a smidge more, would do the trick. :)
I think, with more weight, she should be able to turn into a chunk. Lacey has the same wide chest and she's often mistaken for a QH due to her muscling.
She is SO cute. I just can't get over her. So jealous of you! Lol And I love her halter, such a gorgeous color.
Do you know her breeding? She just looks like Lacey so much, I can't even get over it.
The only thing I can see that really sticks out to me about her conformation is that she's really post-legged behind. Lacey has the same thing though and it hasn't hindered her, I think it's pretty common with Arabs.
The other thing I see, that's also pretty common in Arabs, is she has a bit of a weak booty. I'd like to see her point of buttock-point of croup and point of buttock-stifle be just a bit longer. It's really not bad at all though. She has a nice short back and a super shoulder angle.
I think she'll weigh more than you think. Lacey averages about 1000lbs and she's only 14.1hh. She is a bit of a fatty, but even when she's "thin" (aka, ribs showing a bit, that sorta thing) she's about 900lbs.
