From what I can see it looks like some of your 2 min gestures suffer from being re-worked a little too much. I can see (much like my own) you have a little less confidence in the limbs, which I'm interpreting because of the number of sketchy lines you use. The 30 second poses feel a little too simplistic in the curves, with a lot of very straight lines between the C and S curves. I think you could benefit from either re-watching the lesson or initially just trying to reproduce what your seeing at first, just to get feeling of the line work.
