Kasumi the Elf's Body; Need Help

I’ve been working on the body, and trying to make it a good one for a change this time around. The pictures on the addresses show it in its very early stages, so that’s why I’ve left most wireframes empty, in order to leave it in the loosest stages possible(and the heads along the side are my yardsticks for when I start proportioning the reference body to the Dream of Doll type).

Addresses:
Front: http://www.deviantart.com/deviation/19495662/
Side: http://www.deviantart.com/deviation/19495691/
Back: http://www.deviantart.com/deviation/19495866/

Do I have my line flow right? How do you make the buttocks or the clavicle? What about the shoulder muscles? Those parts have me rather confused. Also, what about the crotch and the interior of the leg?

Help and constructive criticism is very appreciated!

P.S. Are there any lines diagrams around, showing you the flow of the muscles in the way they would be in wireframe? I’ll be grateful if you could find me one!

Hope that helps.
