yeh!, the walltorches looks kinda plain. oops, I noticed that they're also upsidedown...hehe... Would be cool to use models for them, but I rather leave that to last.
I'll try to get some more contrast out of the lightning. It indeed looks as mazy said, a little bland. I must also complete the layout in my head. But I think I'll make this map a small sp scenario, mostly because im rather novice in sp-mapping.
