Concept artwork by Andrew Baker of Radagast the Brown with Rhosgobel rabbit from "The Hobbit: An Unexpected Journey" (2012). Radagast's final costume as completed for filming was far less symmetrical and more unkempt, emphasizing his disregard for personal appearance and his somewhat scatterbrained nature.
Radagast the Brown in vector form. I never thought I'd see such an illustration from the LOTR universe look so... Disney. Not that it's a bad thing, I actually think it's a really cute look that can be pretty hard to pull off. Again like the Gandalf image I posted before this, the artist used a number of simple tools to make this an attractive piece.
