OBSERVATION
Most Dynamic: 1 and 5 (they suggest that she herself moves a lot during fights)
Most Majestic: 6 (she doesn´t move a lot, she lets her puppets do the work)
Hybrid of both: 2 and 4
IMPROVEMENTS
1: her expression is too vague
2: pretty good, but not clear if she is a villain yet
3: disregard this
4: play with head rotation and face expression, maybe combine the lower body of 4 with the upper body of 6
5: this would be probably chosen if it was to become a LoL skin
6: here the puppets dominate a lot of space... but it´s a very nice pose
Besides all that, fantastic work!
