I have to object to being done. you're missing out on a lot of cool details and environment choices. Even if you don't have the ability to model or create particles you can still do a lot more with decals, textures, and basic effect brushes in hammer.
If your visleafs are setup properly you can afford to put in some more detail than what you currently have. Go the extra mile.
It also appears that you are not using the advanced lighting compiling parameters causing lighting problems on your models. For quick compiles I of course would not use it but I am assuming that you are not aware of this at all for the final compile?
You mentioned some people helping you out with detailing. Will they be addressing the problem or is the map in fact "done".
