Well he's so far around on the jump that being slightly forward on the blade is hardly an issue. That landing is actually perfect with the music, the way the skate grips and gently rocks back, reflecting the energetic beat of the piano note. I wouldn't say anything is really wrong with his posture either, it's right in line with the blade. Jumping in the style of the music is something people should do more of.
style of the music : ? music is never slouched
