The background/ effect have great potential, but you could have used it way better. The lighting in the foreground. The Spartan looks way too unreal, and it is too bright. Moreover, you should not have used hayabuse body, Normally I do not care about the armor, but this really ruins it. The Spartan looks way too... (vocabulary fail) fat.
if it were to have a gloomy/juicy effect it would be spectacular, looks like sandbox maybe? so it's possible, i'd definitely try to duplicate this with those effects
