I love what you've posted out so far, Katie, I feel and I think, that you're making fine progress so far. I've checked out images 4 and 6, and I think the poses- in part or in whole-still hold more clearly in the forms (actually, a whole lot more in image 4 than image 6)
But, if I was to point out one whole issue or two, then it would be that some or several of the poses are a mite too choppier in the line quality in the gestures-which us artists have to deal with every day for the rest of our careers, and our lives. Why don't you please do your first newest 67 minutes (4020 seconds/1 hour 7 minutes) of 30 seconds of life figural poses?????????
Why????????? As a result, even with three different flips, your poses will become more bolder and more forceful in their storytelling content, especially in their backs--Not to mention the fact, that even when you sketch them out standing up, it tends to free us artists and drawers up into using our whole shoulders, rather than our whole wrists.
Hope you've found that completely and totally ducky, beneficial and conducive to artistry.
