Everything is confusing and difficult the read except for the images of the authors. It even took me a while to understand the shades of colors behind their images...
I would suggest keeping these images but showing the entire data in a different way.
I made a rough image of how it would look better:
The things I would change:
1) It's difficult to see the length of the carreer of each author in the original viz. If would show their length as a line that could be sized by the amount of prices they won.
2) Since I like the images, I'm keeping them in the middle of each line
3) The height of each line is determined by looking at the time they wake up, strangely that's one of the most important things in the original viz
4) The underlying tooltip shows the amount of books that were published and in which category by using a bar chart in the tooltip (Bar Charts in Tooltips | Tableau Software))
Their awards can also be shown in this tooltip.
