Some basic polish things I noticed about the current in-game HUD.

The "Filler" walls and life bar do not line up with the walls of the nearby hero portait and inventory. They are off by about 10 pixels each.

Also, on the left filler wall there is black underneath while on the right there is grey consistent with the theme. The black on the left is just blank space where the filler should extend.

EDIT: HUD* Polish tweaks..
