I really hope you re-consider using this night theme, good competitive maps have never been set at night because of visibility issues. Castle, Rails, and Mist have all been forgotten about and we're never intended for serious competitive play, so why put de_lite in that weird mix of maps? de_lite was a phenomenal map in 1.6 so why change that by giving it a completely new look, for gods sakes don't kill this map by giving it a night theme, just keep it set in daylight just like your version of de_season.
Also their is a serious amount of ambient noise in the updated workshop version, especially around middle.
