I traced over screen shots of the front and rear views then combined them and drew another outline. Then I tried to figure out the proportions because it looked like the Guards might have been kneeling, and adjusted the drawing from there.
Looks very good. Can't really comment on how accurate is as my experience isn't that great with WC, but the modelling looks very smooth indeed. Also makes me a little jealous. I've never been able to successfully create humanoid models.
part of the reason I used the HL2 rig was to see if it would work with rough Kilrathi leg bone/joint locations once imported.
I assume it can work alright as long as there isn't major use of the foot roll in the HL2 game, since the ankle is located much higher then before.
Or I can just weight the foot bone out of the weight map and simply use the shin to deform the remaining lower body.
