really nice shading, but proportions are kind of off. I'm betting that the heads are too big.
Also, if you applied enough pressure to pierce through armour your hand either would be in the gut because of impulse, or, if it was slow motion, awkwardly angled because given how high the tip of the sword red probably aimed from low point; she could have readjusted the grip but this would mean that at some point she just left sword in the blue lady, which is not very nice.
Pierced cape suggest swift motion, which means that she pulled out the hand out of her stomach, dragging sword with it. Yikes.
