pistachio: Yes, I highly recommend that book, I have found it to be excellent. Very logical and adaptable.
Is there a time restriction on your gestures (like 30 or 60 seconds), or are they unbounded?
I find them to be quite good. I have a problem of being too concerned with contours, proportions and specific structures when working with gesture. I think I'm slowly weeding that out though, but you seem to have a great level of abstraction. The line weights seem a little odd though, they get super fat in some places without really communicating anything (to me, anyway).
As for you critiques, I shall do a detailed double check against the reference. To be clear, the dark line running up her back is not her spine, but a muscle (that I don't know the name of!!!

). The spine is only slightly indicated by the couple of very slight shadow lines to the right of that straight line (she has a very pronounced bumpiness to her spine).
Spartan Camp sounds cool, SHALL CHECK OUT.
