Try flipping the image horizontally. That sometimes makes errors easier to spot.
The legs and shoulders are parallel to the ground, but if you are trying to make the character in perspective, the hips and shoulders should be angled slightly. The far leg will appear shorter than the other.
Draw a horizon line to the right of the character, then draw straight lines from that point to intersect the shoulders, hips, hands, and feet. You might also want to try imagining a bisecting vertical contour line down the planar faces of the character's head and torso.
