Your basic form is really good. I think the problem in the thigh area could be aleviated if you added more complexity to the cage. This would allow you to drag more points and round things out. In Modo you could add complexty to a cage in the area you wish by beveling or by using the knife tool. There are some problems with both approaches. Beveling will distort your shape and it will need to be reworked. The knife may create ngons that you'll need to split manually (unless you plan to freeze the model.) The best example of an ultra-efficient topology in the subpatch form that I've ever seen is patorak's 'Plain Jane.' He posted some useful images (including side and front views of the cage) that are now deep in this thread. My stuff is chaos by comparison, but I suspect I can make it work anyway.
