I was going with a "golden eagle" theme, and had put the character in a pose where he was to have an eagle landing on right arm. I didn't get to that point yet. Right before posting, I was wondering why that eagle symbol on the sword looked familiar... Unfortunately, after a Google search I found it's a symbol used by.... the Nazis. (They were some stylish bastards.) So, needless to say the symbol would have to change, as well as the gesture and size of the right arm. I'm sure he'd also benefit from some legs at some point.
Edit: Wow, it really looks like the arm of a small child..
