Have you considered the difference?
business/ clients wishes VS personal project
I assumed final fully PBR interactive application with all the details (color & light studies, interactive materials, day to night...) no generic or freebie stuff (rights for commercial redistribution passed to client).
Working hours are 8h per day/ 5-6 days per week, taxes, insurance, accounting, holiday, vacations... and so on.
But don't mind me, just another brick in the wall.
edit...
Oh, nice tackle... National library M~R competition stuff... hope to see your vision.
