So a little random back story:
Jo's brother is actually in the Equestrian Guard. He is also an earth pony, and pretty close to Jo's size.
So what else is a good brother like Jo to do?
Try on his armor of course.
Jo had always wanted to join the Guard, but made some good at that point in time decisions, and didn't.
That's why he's so happy to have Guard armor on, even though he's not in it.

His hair is not up to regulations, as you can see.

Also, I think my line art is getting nicer. My hand and arm were getting pretty tired towards the end of this, and I ended up fixing his butt like 3 times.
