The first one has some pretty nice weapon art, but in the second pic you completely gave it away with the power drain in the bottom right corner. Next time you may want to zoom in and cut it out of the screenshot.
pic 1 is some pretty nice 'weapon art', and pic 2's camera angle is extremely shitty. you can see the power drain easily [unless the power drain thing was planned]. either zoom in further or try to capture the pic from a different angle [which would be difficult, because you would end up with a less intense effect]. you should remake pic 2. make a raised platform and have the spartan do his ****, and then throw the power drain so it lands below the platform. ur result: no power drain in the pic, but still an 'intense' effect.
