Plane icon, landing page UI: Mixpanel

Hello friends! Here is progress on some landing page elements with a freshly updated plane. We'll be launching it soon @Mixpanel. Let me know what you think. :)

Thanks to @Prathyush @Matt, @Brian and @Jeff for the constructive critique on the previous icon. This inspired me to take a new direction to give the plane a more unique style.
