Oh, Garrus. Everything needs to be calibrated. Including hyper advanced, interdimensional space ships, piloted by space dragons with Jedi powers, you know nothing about.
Your Garrus looks spot on if you ask me. Correct me if I'm wrong but so far I've seen maybe one or two images of Emperor Kedzuel that depicts his whole body, maybe it's time to remedy that. Or maybe something of a reference sheet? Most of your other characters have one, can't make him feel left out.
Hey. Garrus is boss. I once went through a mission with him, Ashley, and my infiltrator, all using sniper rifles. Oh dear god the head-shots. It was horrifying. Those poor enemies never knew what hit them. And hey, his calibrations let you nail targets dead on. Gotta appreciate that.
Annnd Garrus just broke the technomancy screen with but a question. Nice job Garrus, go ahead and keep pestering the Emperor (all in a sarcastic tone). Love the visual gag of the technomancy screen breaking as the emperor says "dammit Garrus!"
