Earthshine on the crescent moon

I've been wanting to take a photo of earthshine for a long time, and tonight was my first chance! Earthshine is light from the sun reflecting off the Earth to light up the part of the moon not lit directly by the sun. Sun > Earth > Moon > Earth > Camera.

"Earthshine can be best seen during the crescent phases (the 1-5 day period before or after a New Moon). During this time the sun is mostly behind the moon from our perspective and bathing the Earth in a lot of direct light that is reflected onto the shadowed parts of the moon." (Source)

It stands to reason that other conditions can increase the amount of earthshine on the moon, such as snow cover, reflective clouds, or maybe even the Atlantic Ocean.
