Leg anatomy... aaaaargh

I have worked on the leg anatomy today, whilst the hobgoblin is very thin on the artwork, he would still have leg muscles which are quite defined, all be it they aren't very muscular.

I have used various books about anatomy to look at the leg muscle structure. I am not completely happy with them, but what I have done is a good foundation to build on. The thighs are not seen, however their form will define the bottom of the coat which drapes around them so it is important that I have the right form.
