I'm glad our article have helped you with your gestures. :) I took a look at them and you definitely have the basics down. It might be worth noting a few things.
First, try to incorporate more curves. A lot of your sketches look a bit blocky, which actually hinders the flow of a gesture. Is there anything on your body that is square or overly straight? The shapes can help you get a base down, but ideally you'd accomplish a gesture in a few, curved strokes.
Swen is one of our members on the forums who has gestures down to the T. Why not head over and take a look at this gestures? He includes useful notes that can help you out. :)
If you look between your gesture and Swen's, you'll probably see what I mean with incorporating more curves. Don't be afraid to draw an arm with a single curved line. The focus is proportion and motion. It's okay to draw over your lines a few times when you do this!
