This map should work perfectly in instagib or ffa/duel.
I like the layout, and the variations in geometry. Only thing that bothers me is the lighting, there are no shadows at all, looks almost like fullbright mode.
Try to set /ambient and /skylight to lower settings, i.E. /ambient 10 and /skylight to something between 50-70 (while 70 is almost too bright again).
Also i noticed some flaws regarding the clip material, there still are some spots where the clip material is either missing respectively where it is not on the same vertical level (corners in both cases).
Other than that, nice work, and if i could make the decisions of which maps to get included, this would be a candidate for the next release for sure.
4/5 :D
