Muambator icon

This is the icon of Muambator, a brazilian package tracking app:

The Muambator service has a mascot and his name is "Flecha", ironically a turtle! (a fast turtle in this case) :)
In the Muambator service, "Flecha" is responsible for tracking and delivering orders to users.

The previous mascot was a bit old (http://d.pr/i/9AQb), so I tried to make an icon that could be more visually appealing and easier to recognize.
