i think some particle would really spice it up. It looks good, but sort of monotone or monotonous (is this an english word?) Anyways, if u added some dripping water from within the wall and aceiling or something, wold look nice. Mabe some occasional sprites on floor, such as dirt, and/or blood, but it depends on ur style. Just to make it so the users eyes will jump from thing to thing, instead of looking at the tunnels. But its just my opinion.


Thanq for your attention.
