A straightforward Rhea design I made to put on shirts and stuff. Nothin' fancy, just Rhea!

You can buy it here on my Design by Humans shop: http://www.designbyhumans.com/shop/rhea-snaketail/144028/
There's also a lineart only version if you're looking for something a bit more subtle: http://www.designbyhumans.com/shop/rhea-snaketail-lineart/144622/
