Keynesian Economics Final(s)

So I did a final for one of my sketches and because I wasn't so sure of the message got across (the fact that it's about Keynesian Economics) I decided to make a second, slightly more literal illustration about the matter. There IS a tardis in both, but the in second illustration it got almost completely darkened out...oh well. I kinda like both in their own way, and I got to try out digital painting again. YAY....?
