That link is an amiable job, KatieOfConrad.
I think you're doing a great job on your 1 minute poses, because of how dynamic, energetic, and vital they look and feel.
Still, I've got one tiny improvement: I love the fluidity of those lines with feeling, but I'm not getting enough feeling and cartooniness from those lines. Why don't you please be more confident with those edges, in 4 minutes of 59 second warm-up poses?
The reason why you'd do these is because, those lines will become smoother and bolder, just a teeny-weeny bit, even if they loose form and detail. As a result, this could be most vital into boiling things down to their basic foundation.
Good luck to you, and I hope you'll find this completely and totally approved by all of us.
