Magical Goat-Horses Picture

Whaat, you guys have never gotten the urge to draw mythological beasts before? These three came from a conversation between my friends a while ago. Long story short, Rodney can travel through time using a magical rainbow vortex that he's able to shoot out of his horn and he fights crime. Yep. Rodney looks like the Jolly Green Giant's noble steed or something. Please critique if you can! Thank you!

Rodney, Boris and Lynette are mine. The Jolly Green Giant is not.
