Thanks - glad you like it (because I'm really quite pleased with it! XD)
I'm not sure about the back portion, really...if you look at a real-life magpie robin, it's something like a small rat. XD It doesn't matter, really!
(And it's a he, by the way...girl magpie robins are grey with a lovely peach tummy. ;) I ought've painted a pair together - maybe I'll do that with the next bookmark!)
This is so cool :D I love unique gryphs, so cool! What is she, Magpie Robin/mouse? Cool tail and backlegs, whatever she be <: And the perch she's climbing on is just as neato looking. I love your style of shading and highlighting! o:
