Damn, you don't have to flex your phone on us. :P Anyways, nice work so far. Your rhythm is pretty nice. I feel like that your lines are a bit too light. Once you get the gesture right, try to strengthen the most prominent lines. It will make the sketch much easier to understand. Also, some of your drawings seem like they are off-balance. To fix that, make a vertical line from the sternum. That line should also hit the heel of the leg, which you have the weight on. If it's not hitting the heel, the body is probably unbalanced. Hope I could help! Keep up the great work! :)
