1 Minute gestures critique

First critique for quick poses (1 minute)

You are able to get a good and proportionate reading of each pose in such a short amount of time! 

From what I see from these 4 drawings, it looks as if you run through a system of drawing each part of the body (ovals for each limb, marks for the chest muscles, etc). That isn't bad, but I would suggest you don't always stick to that. Maybe you can look for the overall curve in the spine or in the arms/legs as a whole? It has helped me in the past to keep some of the limbs as just curves, so I don't get too focused on the complex shapes that all the muscle and bone detail adds up to create. It is better for quick studies, I think. 
I feel like the poses are a bit stiff, and maybe that could help.
Good work though, keep it up!
