i think that you really need to cahnge your wireframe. heres the one that ive come up with a while ago for my own use; or something similar (i change it all the time but this is the basic construction), and its not the most accurate but its much more servicible than what you are using
the most important thing here is the four diamonds (badly drawn in mine, they should be roughly equal, highlighted on the right). if its unclear, heres the locations written out:
1st diamond top point: inside the mouth, right where the throat begins
1st diamond top sides can be used to form the trapezius, which does stuff like hold up the head
1st diamond middle points: hollow where the pectorals meet the deltiod, just under the collarbone. poke yourself to find exactly where it is on you, youll know when you find it (its a wicked pressure point)
2nd diamond top point: the pit where the collarbones meet. dont poke around to find it you can gag
the 3 points here connect to create the shoulder line in the central figure. this line is _incredibly_ important
2nd diamond middle points: nipples.
1st diamond bottom point: lower part of the sternum, just above the solar plexus.
3rd diamond middle points: ribs terminate
2nd diamond bottom point: belly button. in real life, this is actually a couple inches too high, the belly button fits best in the center of the smaller diamond just below this point
4th diamond central points: that point on your pelvis that sticks out on hot girls and boys
3rd diamond bottom point: this point had really little or no value, middle of last pair of abs
these points connect to crreate the pelvis line, equal in imporatnce to the shoulder line to balance.
4th diamond bottom point: the most important point for obvious reasons
hope this helps a little, ideally you should develope your own way of working, but you also need to come up with something that works, and your current setup lacks quite a lot for good positioning and anatomy
PS: terly you cut the arms short on your edit. not to pick on you but this is a common mistake. hands should fall in the middle of the upper leg, not starting at the belt line like yours are here
