Wyvern

This drawing started out as me trying to draw an "anatomical correct" dragon, but after 8hours of sitting up straight and drawing without a singel stop, I ended up with a wyvern instead. (For those of you that don't know, the differance is that dragons have eigther 4legs and 2wings or 2legs, 2arms and 2wings, while wyverns have only 2legs and 2wings.)
And I don't think I've ever been more proud of anything I have created before
