https://github.com/numixproject/numix-core/blob/master/icons/circle/48/dropbox.svg Dropbox has updated their design twice, this icon should be adapted to the current design. Original icon: 

App name: `DROPBOX`, `https://www.dropbox.com/` Icon name: `com.dropbox.Client`  Description: `PROVIDE A FILES MANAGER PLUGIN FOR FILES SAVED ON DROPBOX`  The old icon is the light one...

I created an icon that looks at home in Linux distros that use Gnome's Adwaita. Maybe you can make use of it, maybe not.
