I'm glad you liked it.
About the looking downward in the fighting stance: it depends on the style of combat you want your character to use. If you go for something like boxing, kickboxing or mixed martial arts, the default fighting stance is to lower the head so your chin gets about at the level of your shoulders. This way round attacks like hooks and roundhouse kicks will probably hit your shoulders or have so little space that they have a hard time reaching your chin. I could explain why protecting the chin is so important but I think this is not the point here.
Also, when you fight, you usually don't look your opponent in the eye, unless you want to play some mental game. You usually look at the chest area and don't focus on anything in particular. This way your peripheral vision allows you to see leg attacks and arm attacks coming at you. If you look your opponent in the eye, you are exposed to lower attacks because they are a little out of your vision range. If you focus on something in particular, your eye will follow this target and forget about the rest. Ok ok, I'm going too far again.
But anyway, you can trust me on this, I've got 24 years of several martial arts behind me to back it up.
So, it's just to say that I made the character look down on purpose because I gave him a boxing like fighting stance.
