nice map, can't wait to play it, because im such a harvest fan, played it for days.
but i have some crits.
1. Change the water texture of the lake to some ep2 texture, because the texture you've used now is so ugly and i've seen it to often.
2. You should use more ep2 content because it just looks better and i can't stand the standard hl2 content it just looks dead and boring.
3. also you should ask deathy for some better light settings, he showed me some really good comparison screenshots from his old to his new settings, and i think you can easily adapt his to yours

, because the current settings look near to fullbright.
