Don't beat yourself down like that... you've done worst :)

But as real criticism, there's almost no excuse for a level visibility to be that low. Also the slide/fall that kills you without way to see it coming at first is usually not the most fun thing, it just kills you once for no fault of your own then after the first death you just know it's coming so it's not much of an interesting obstacle at that point. Finally I don't really see the point in those bigs dustblocks mass, don't think it adds anything to the map.

Some of your recent maps seemed to get a bit better so I'm a bit surprised to see you come up with this.
