Hmmm...you should make it more obvious that the sword pierced through them. Like putting the sword "towards the front" where we can see the place on his/her body where the sword entered. It's kind of hard to explain but from this point of view it just looks like one of those cheap movie acting where they put the sword behind the two actors and expect you to believe the sword has pierced them...Do you know what I mean?
From all aspects it's beautiful!I like the light in the background(is it the dawn or an explotion?!)and the weapons which are pinched on ground.I like this contrast...war and death against love and light<3Nice calmful faces!And I love the way this light fades into the darkness of night.You have painted the different tones quite discernibleKeep up the good work
(PS.I hope the weapons in bg are pinched on ground and not in other dead bodiesT__T)
