Well, they certainly look like they are "progressing" very nicely. If it were me, I wouldn't be able to resist the urge to back the front toes off a little bit and "monitor" the growth thereafter and rasp a little more if it looked "appropriate".
If the heels are just a smidge above (longer than) the frogs, and the frogs currently look like the nice "after trim" pics above, then I would guess they are not to long. JMO.
Just as a matter of interest, the angle of the bars on the right front vs the left front are considerably different, and the heels appear to be closer together in one than the other - which could just be the photo. Maybe her fronts were different lengths for a bit? She favored one? It is nice they are "on their way", now.
