Andrew, Nice snatches! nothing wrong that I can see.
The windmill from James suffers a pretty common problem and i thought i'd taught him better!
The foot under the Kb is facing almost straight forward, when he tries to fold sideways the ITB restricts the movement and he leans across to the other foot.
If you turn both feet out in the same direction but keep your hips facing "forward" then you can push the hip under the kettlebell out to the side more and keep the weight on the heel of the foot under the KB more. Not such an issue with a light weight but if you try a windmill with say 40kg and you lean too far across you'll end up screwed right into the ground with a kettlebell holding your head down.
Next time i see you guys i'll show you what i mean.
