The majority of what Ive learned from mapping has come from just doing it. Theres some things even tutorials cant teach you. I remember reading somewhere a while ago that the worst thing about being a one person mod team is theres no graphic designers to design your level for you. Part of being proficient in mapping in seeing the finished product in your head when really all you have down is several nodraw blocks.
