I've never been a big fan of the VIP/Assassination mods, but this map is pretty damned good.
Only problem I have with it is the 3d skybox. I thought the choice of textures was rather bland and you didn't correctly scale them down (1/16 or 1/32 size) using the texture application tool.
But your use of detail and props was great.
Maybe had a few too many decals for I got this error constantly in console :
R_DrawDecalsAll: overflowing m_aBatches. Reduce # of decals in the scene.
My favorite part of this map was your perfect use of the tools/playerclip texture, most custom maps are easily exploitable, but this one is even better then the Valve defaults in that regard.
Overall a great job, may even want to update your de_hiekka with these textures for it looks A LOT better without the dust textures.
