Tall bookcase conversion to base and top

I built a tall bookcase for our son in early 2004. Since then he’s moved a few times and now he is a first-time homeowner. It was hard to move this book case, so to make something that seemed more in style with a 1950 house, I decided to rebuild it as two pieces, so in early January 2020 I cut the top off where I had a fixed shelf 30″ up from the bottom. Then I added 4″ of depth to the bottom section, added 2 drawers, and doors, and solid top glued up from 3 pieces of Red Oak. Photographic history below:
