Layer masks are huge. The idea is great, but the execution is a bit lacking. If you were to put Optimus' fist infront of the other guy and put the other guys arm behind Optimus it would tangle the 2 in combat much better. As for text I like to use an outer glow effect, but switch the color to black and the blend type to multiply so it looks more like a shadow. Then I drop the opacity a bit and make it larger so it blends more and it's not as noticeable
not sure what you mean nugget by "If you were to put Optimus' fist infront of the other guy and put the other guys arm behind Optimus it would tangle the 2 in combat much better" his arm is grabing the shoulder and the guys arm is behind him with layer masks and overlays.
