Feron, even though it's been said before, i thought i should agree that your heads seem quite small. The pose in the newest update seems rather awkward, what are you trying to convey? It kinda seems like you're drawing the figure as you go along the body (Eg. starting at the head), rather than sketching out a simple guide first. It is probably best to get the body proportions and the figure's pose fixed before you go onto muscle shapes etc.
