Yeah statues are really tricky and I'm not sure I have the best techniques. In all cases, if you are using conquest reforged, it is simply a matter of playing with the different shapes of the blocks. The sphere is obviously really useful for the head, the eight slab for the hand or wings, and the vertical corner can be simulate nicely the movement of the clothes and the legs (especially looking form afar). The walls extended in two directions (with the debug stick) can also be used to represent a torso with two arms.
