This is a Shepard Costume for people who are fans of Mass Effect 3.
I think this was actually a good representation of him in Minecraft! :D

_______________|SHORT BIO|_______________

One month after defeating Sovereign, Shepard's ship, the SSV Normandy is destroyed by an unknown warship, killing Shepard. Shepard's body was recovered by Cerberus, a rogue human agency who had been keeping tabs on Shepard for the Commander's actions in Mass Effect. Over the course of two years, Shepard is rebuilt through Cerberus's Lazarus Project, headed by future squad mate operative Miranda Lawson, which uses a combination of cutting edge cybernetics and nanotechnology. Upon making a sufficient recovery, Shepard investigates the disappearance of human colonies.
