She appears to be a stocky person in boxy looking clothing. It might be influencing the perspective.

There's some perspective nonsense going on. She's in a crouched, leaning position and we're viewing it from the direction she's leaning instead of the side like in the photo

Her arms, too!

Its a bronze statue. The artist probably had a small block of bronze and misjudged some when he started carving

Yeah, there's a lot wrong with the statue. Considering the sculptor had only the same picture we see to go from, I don't know why it's so off.

Apart from the too short legs, the other three things that stand out most to me are the woman's expression, she's much more determined in the photo. The coat is too long, it should be a jacket. And, finally, the bag should not be ahead of the arm swing, it should trail, just as it does in the photo, because physics.
