Hi! Your ambiences are nice everywhere. The wide screen one is particularly interesting because amongst the 1000 contenders here this is roughly the only one in this format, with a small hero yet instantly identifiable. And again, it has a great mood. Maybe it lack a bit of the "war" aspect, but you can have it be replacing foe's gun by a gatling.
If you stay with your last batch, i would say the most theatral one, bottom right.
Cheers!
