It's looking a lot better! It's cool to see it progress like that.
I agree with what Chucky said about the legs, also, they look a little... formless... or I dunno... that's not the right word... lemme think...
They don't look like they have bones and muscles, it looks like you've drawn way more upper body studies than legs basically. Legs have lots of nice curves and asymetrical bitses and stuff...
Here's a crude recreation of something I saw one of my tutors draw when he was helping someone else. Sorry... I'm terribly messy with my drawings so I dunno if this is clear or not but it really really helped me... look for these kinda things in the whole human body too, not just legs:
Also... now... please don't be offended by me saying this... cos I'm certainly not a great life artist, and I don't know you personally so I can't see your working methods... but I think I noticed something about your art. Just based on that one life drawing picture you got there (which looks like it's from a photo), and let me say, it's a really good drawing, don't get me wrong, but just looking at that, it looks to me that you've learnt to draw surfaces more than structures.
The Animator's Survival Kit mentions something about this... I would go get it but... it's upstairs and I can't be bothered : p anyway... it's like, you can draw skin tones and shading really nicely, and copy the photo really well, and produce beautiful results. But unfortunately that's not helpful for animators. Animator's life drawings are far more... technical, focusing largely on skeletal and muscle structure. It does look like, from studying the surface, you're learnt a fair bit about anatomy and stuff but if you haven't already (and again, I'm making this observation based purely on assumptions based on what little you've shown us here in this thread, you may very well be doing this already, in which case you have every right to shut me up!) you should learn about the skeleton, invent a good "formula" for a male and female skeleton and muscle structure (again, Andrew Loomis is great for this).
So yeah.... I might be assuming too much, and I apologise if I am but you're obviously a talented person, and I would like to see such talent reach it's potential.
