Beautiful
You did great highlightinh the face. Nothing better to turn an otherwise boring library into a memorable place than a smart girl, with smarter eyes, and even smarter hair :)
I see an irony here.
Pretty girls are usually considered dumb and artificial. The way you painted the books on the shelves (no marks, etc), makes the girl look very realistic and the books not so much. It made me remember the library of Silas Lapham in William Dean Howells' novel.
