Owls in a Library Window

Two owls sit on the sill of an old library window, with shelves of indistinct old books and warm lamp light behind them.

The two birds make a pair, but their feathers and poses still give you separate shapes to follow. Build the window sill next, then sort the books by spine color without relying on titles. Warm lamp light catches the glass and wood, while darker shelves provide a steady background around the owls. When owls in a library window is complete, its nearby shadows and highlights should point naturally towards the remaining pieces.
