Elderly man reading atop books in a vast old library

Make a small portly old man in a giant library holding an open book and reading it while sitting on a tall stack of old books. Make the library at least 3 stories high with a beautiful spiral staircase. The inside of the library is old and full of 1000s of books. Have sunlight pouring in through the window a showing on the man. The room is a giant cavity of books and shelves. Put the man as a center of influence in the picture using the law of thirds and the golden ratio. Make it photo realistic in 5k. Place the man off center in the room
