I really liked all your visualizations - you did a great job displaying all the data. The only advice I have is be careful of small things such as font sizes and graph sizes. The font in "Earnings vs. Revenue by Quarter" bar chart was quite large, which affected the size of the legend overlapping the actual bars. I definitely suggest looking out for smaller things like this to make sure everything looks nice and readable to whoever is viewing your visualization.
