These are both kinda boring IMO... The background is way overused and there are just soo many shots that have an explosion of a plasma grenade or a vehicle in front of that wall. Other than seeing these a ton, I think that they are pretty decent shots but try to do something more original.
Have you seen the pose in first screenshot before? or the streak that makes it look like the melee is in motion?
Yeah... It's just a guy meleeing with the sniper and the streak comes from the plasma grenade explosion.
the only reson im intriguide (spelling?) by electtric is because i dont know what the background is. wraith exploding or something, but it looks... just weird.
