Kris has been taking some cues from Ralsei, I see
Seems his long gun's an M4 of some kind, and the short gun's a cartoony revolver. Revolver cylinder looks like you just copy-pasted the barrel and called it a day, and M4's looking fine all-around.
Colour scheme on both of them is pretty solid, though. Pose with the revolver's looking nice - seems Kris is getting ready to reload.
