This is Guard from my short story. The design for him was somewhat of a challenge for me because I really wanted to make sure that although he is made of armor, he could still show emotion in his face; after all, hes not always going to be in battle mode while hanging out with Quinn. 

The way I ended up doing this was giving him a knight's helmet that when up, showed his normal face and while down, would turn his face into something more formidable looking while in a fight. 

Even though he ended up looking more like a medieval knight, I initially wanted to add a hint of World War II soldier to him as well to show the type of climate he was created in. I made it so his helmet looks as though it was built around a German helmet but aside from that, I didn't ad much else. I hope to expand on this idea a bit more while modeling him but for now this design is good to start from.
