ok. the sky's black because i'm taking the pics outside of the skybox. Those pics WEREN'T there, to show you the stinking skybox, which i believe is day_07_01 or something like that. The pics were there to show the map geometry.
As for the train, Yeah, i know, no train tracks, i'm making them soon, its freaking a5! if you expect it to be perfect, it won't be, not even yler's or nerdboy's maps are perfect at a-stinking-5.
