Weird graphics layering

[bricks]

Right now, the character tile draws really strangely. The health bar should be above my feet, not under it, and map features to my north should be drawn beneath me (it looks really obvious in some places, like The Deep Bellow).

Also, the character tile could be shifted up a bit, so it isn't standing right on the bottom of the tile, and in general, floors should be darker and duller so the character tile pops out.
