Here is a set of some of the more presentable gesture sketches I've been doing the past couple of weeks. I'm sort of stumped on how to make the 30 second gestures better without getting bogged down in mannequinization (which I find hazardous when reference photo lighting obscures the anatomy and leaves me having to make rapid guesses). Anyway, I really would appreciate people sharing their thoughts on these.
The more detailed studies you've drawn are absolutely gorgeous! Save for a few minor proportion/placement mishaps, you're definitely right on track. :)
As for the mannequinization you mention, that is in some ways the point. There's a minimalist approach to gestures that has you put down a recognizable, proportioned and dynamic figure in just a few strokes of the pencil. It's true you can't always see every limb and how it's attached, but that's part of the gesture challenge: training your brain to recognize and in some cases make 'best guesses' in just a second or two before moving on to a new gesture.
From what I gather, part of the problem lies with the material we have at this time. We're working on expanding our library and replacing most of the older photography with photographs that we commissioned ourselves. That will probably include images with less 'guesswork' and better lighting. :)
Your gestures look very scribbly/busy, and in many places aren't recognizable which makes it difficult for yourself and others to see what the pose and dynamics are. In case you haven't seen them yet, we have some useful articles to help people get gestures down. I know you're not a fan of the style displayed there, but it can be helpful if you'd like to give it a shot!
