Overall, this appears to be a pretty darn nice filly-and I agree, her weight looks FINE! From the photos submitted, it appears to me that she might be a bit thick in the throatlatch, and not deep enough through the heart girth(amazing how often I see this in miniatures..?)..depth through the heartgirth, along with well-sprung ribs, are vital for heart and lung capacity, and therefore, stamina. I also believe that the filly has TOO much toe, especially on the hind feet, according to the photos. I wouldn't recommend more heel, but less toe. It appears to me that the way she is trimmed makes her pasterns TOO angled, which means too much stress on the suspensories,and a higher likelihood of unsoundness, esp. if asked to do serious performance work(such as jumping, or driving.) She is overall nicely balanced, however, with good length and attachment of neck, decent shoulder, strong(and the ever-popular, FLAT!!)coupling/loin, and croup, long and reasonably strong hip, and decent legs, as least as can be seen from only one side. Nice head, feminine and suitable for her size, as a Miniature-also, good clean definition where the neck attaches to the chest. I imagine you are justifiably pleased with her!!
The rather 'extreme' stretched neck with nose pointed UP is NOT conducive to seeing a horse properly, IMO. I understand trying to 'extend' the neck somewhat, for a cleaner line, but I REALLY think it throws the 'picture' out of whack to have the horse's nose in the air!!! An excellent position for showing the 'real' horse in photos is NO stretching, but(for side shots), a pose where the horse's body is directly 'over' its legs, with the front leg on one side SLIGHTLY behind the perpendicular, and the corresponding hind leg SLIGHTLY in front of the perpendicular(this way, you can SEE all 4 legs, but they are not distorted.) Photograph on a level with the horse's torso(which with minis, usually means squatting!), at a good right angle to the plane of the horse's body. The horse may be encouraged to SLIGHTLY extend the head/neck, but keeping it reasonably LEVEL, not "nose up" OR "nose down" to any degree. Front and rear photos should be with the horse well-squared up,on a level surface, and again, not stretched. These are the kind of photos that will be most useful in conveying the horse's ACTUAL conformation--I am not talking about promotional shots(though for me, I'd RATHER see THIS kind of photo, as I want to see the REAL horse!)
Edited to add: I do NOT see this filly as in any way 'over' at the knee; there is a 'fuzziness' of the knee and hock areas in the first photo, and an odd 'dark' area at the knees in the second photo(can't tell if it's actually 'on' her, or just the photo)-but I absolutely don't see her as over at the knee. This doesn't change the fact that I believe she needs the trimming changes I outlined above, however.
