WhatsApp Icon Concepts

These are two concepts for Material Design WhatsApp icons. Personally I am not a WhatsApp user and those icons were a request. However, I thought it'd be interesting to have my own take on them.

Since the app has changed colour with its fairly recent Material Design update I thought I'd make the icon match the app. I don't particularly like the way long shadow looks on the phone icon, so I've made a second variation.
