Figure Drawing critique request

Hello everyone. I've been using this site for about a month now and I just recently made an account. I'm looking for some feedback on some of my most recent class session drawings. I'm an animation student currently working on my body forms to create and develop better looking characters. Here's the link to one of my posts on tumblr. Please tell me what you think. Thanks.
