The screenshots are looking good: the brushwork, the Stalker models/textures and the attention to details are remarkable; good job
But be careful as this open map needs some serious amount of optimization, otherwise it will be unplayable on public servers and your work will go to waste. I noted some low fps values inside the map (i'm not referring to the outside map boundaries shots) but since it's still a WIP, you got time to optimize it before final release.
and the pink HUD does not suit the screenshots
Good luck and awaiting the final version
