Critique 13 yr Paint/QH mare

I loved this horse to death and sadly had to part with her earlier this year. I was hoping you conformation experts could take a look at her and tell me what you think of her conformation just for fun! Thanks in advance!

She was 13 here, she's 15.2 and thought to be paint and QH.

She has a decent shoulder on her
Good depth through her girth area
I personally like her neck and head
Front legs look correct
Back is not a bad length either
Fairly high in the wither, especially considering that she appears to be standing downhill in the photo
Well rounded hindquarters that could use more muscling in my PO
Hard to judge her back legs with the way she is standing, but nothing terrible is standing out & she gives the impression that she would be fairly correct back there as well
Overall a rather well put together mare that could do with muscling ;)

Oh, and yes, she looks to be a Paint to me as well (QH X TB breeding)

Thanks! Yeah she is standing slightly downhill here. That's the best pic I have of her though.
Her withers are very high. I went through dozens of saddles trying to find one with a high enough gullet to fit her.
Thanks!
