High Side Leg RaisePose Reference

The right leg is the only support, straight from hip to heel. The left leg swings outward and upward until the pointed foot reaches roughly head height, knee extended. To keep from tipping toward that lifted leg, the torso bends sideways toward the standing side, so the ribcage and head shift over the support foot. The right arm arcs overhead and frames the crown, extending the sideways bend into one long arc from the standing heel to the fingertips. The left elbow folds and the left hand rests on the inside of the raised knee, closing a small triangle between forearm, thigh and waist. Every limb belongs to the same counterbalance.

Front and back views are where the side leg raise pose reads best: you get the wide open angle between the two legs and the triangle at the knee. From the figure's left side, the raised leg points almost straight at the camera and collapses into a short shape, so that view is a good exercise in foreshortening a thigh and shin. Seen from above, the lifted leg clearly leaves the plane of the hips, and the low angle stretches the standing leg into a tall pillar. Keep the standing hip visibly higher at the outer edge than the waist above it; that small step in the contour is what sells the weight.
