(actually hard to get pelvis pictures not from a cardinal viewing direction)
Have you considered working from a 3D model? (e.g.:

I am starting with gestures. Here are some 45 second gestures(shucks I couldn't complete any of them)
Suggestions: Use a softer pencil for those (5B) and do them on plain paper if you have any. Then, try to not copy contour but rather look for the long rhythms and limit yourself to 4 to 5 confident strokes per gesture (that's almost 10 seconds per stroke which should be enough). Then of course the most important thing, keep drawing. Do not stop after just a handful of gestures. Also check
http://www.proko.com, he explains gesture drawing quite well even in the free versions of his videos.

toons, I hate you
Relax.

Toons need love. Well yeah, I am struggling with them too. Funny thing is, back in school they came easy to me when I scribbled them in my books (even without construction) and nowadays I struggle with construction but that's in everything not just toons... maybe toons do not like being carefully constructed too much?
