One of the pose of practice

Love your exhibition of potential, Terminusumbra, nonetheless, I've got one small appraisal: Would you like to go for 10 29 second sketches, all drawn with your elbow, pretty, pretty, pretty, pretty, pretty, pretty please, please, please, please, please, please?????? The reason is in behalf of, your line mileage will look and seem easiest. Hope and pray that it'll give you your most positive results.

It looks good for 30 seconds, though if you would like to try to improve your proportions overall you might want to think about upping the time a bit more, to something like 60 seconds or 2 minutes. I really hopes this helps.

Yes I totally agree with Rachie, at this point I don't think 30 second poses will give you much in terms of capturing the body. Although it's a good exercise to remove the habit of getting stuck in details and find the action in a pose I think 1-2 minute poses would be better for you.

That being said I don't see why your line of action is broken up into two pieces for this pose. The force looks like it's being pushed from the back leg and up, a stronger line from the back foot up to the head would give a better feel, but that's just me! haha It's all subjective in the end. Good luck!
