Most excellent tech demo =) I personally did not have any trouble with the brightness or with discerning foreground and background...but I think that's because there isn't anything to interact with yet, so everything is really background.

Once there are enemies and items and suchlike, we will see how difficult it is to differentiate.
Besides an overall grin of appreciation, I will just say that I found his knees to be surprisingly shiny while I was playing, as bright as his sword and belt buckle. Is it supposed to be ripped pants? If so, you may want to yellow them a bit.
That is all

Good show, good show.
Oh, one other thing -- I thought the standing attack animation had him pausing a little too long after the slash, compared with the crouching one which felt faster. I think the overall time the slash takes is fine, but it feels slow because of the way he holds his sword motionless for a moment after striking. (Like, "haha! I sword you! I am a wolf! *pose*"). I only really notice it if I attack while running.
