It makes the shoulders look a bit tall, but I think on Evo it looks fine since he's the muscle. In fact it makes him look better. I just might have to order an Evo chest from PaB. Also, I was going to say something about it getting in the way of his shoulder armor , but surprisingly it's not a problem; the armor is hollow enough to handle it easily. Does inhibit head movement a bit, though.
e: and you can see some of the circuitry printing through the holes in the 2.0 chest, oh man it's really cool that was a great idea thank you.
