More Complex Perspective Exercises

After doing my first 40 thumbnails for my Invisible Cities project I thought I would do some more perspective exercises, as I found getting the perspective right hard in some of my thumbnails.

Although I don't know if this 5 point perspective exercise would come in useful for my current project, as it gives the effect as if you're looking through a fish eye lens, I wanted to try it as it looks interesting! - I did add some building like shapes though to see the effect of the distortion!
