Hello, Ken_Needs_Help, and welcome aboard. I'm Polyvios, Polyvios Animations, and how are you doing today. I think you're doing a nice job trying to draw out a scene from memory, but I really feel that your potential is really showing through, and therefore, your memoried poses seem too stiff but straight in the lines of action and rhythm. How would you like to please flex you hands and brains with some memory gesture drawing, with half the time looking at the model, while the other half is spent actually drawing from your head??
The reason why you could practice your drawing from memory is because, your poses from imagination will become two things: First of all, to actually observe your reference without actually drawing first, and second to make your pictures from your mind to be drawn less stiff but more fluid but lively, actually. For even more details, there is a YouTube video or two than can actually tell you about way differently than I can at this round, so please take my advice with a little grain of salt.
