The face on the empire general is really beautifully done.
As for the warrior priest, I think the arms look a little off. Also the choice of head is somewhat unorthodox. Sigmarite priests are generally represented as being bald (although I'm not sure if the fluff says they're supposed to all be bald). The sculpting of the robe, however, is spot on.
For the "swinging over the head" pose, I like to use a really dynamic body. You might find these helpful:
The priest in the chainmail has his hammer about as far back as humanly possible. He's pretty exaggerated, but there's a sort of coiled quality to his spine, that suggests a great power about to be unleashed (like when you've drawn back on a bow or slingshot and are about to release). I specifically changed the angle of the waist to get that effect, and I think it works pretty well.
The free company warrior with the axe over his head is even more successful, in my opinion. The aggressive pose of the legs really makes it look like he's about to split somebody's skull to the teeth. You might want to try that set of free company legs because they really lend a sense of dynamism to the model. It should be easy enough for you to sculpt a robe over the legs (you did an excellent job on the robe of the priest) if you choose to go this route.
