Character Design - Animal Mashup

I designed this creature while in the waiting room in a hospital in Sweden, looking through a wildlife magazine.
It's a cross between a cat, a mole and an eagle. The instincts and speed of a cat, the wings of an eagle and the digging ability of a mole. I imagine it's habitat to be a forest or cave. Pretty random concept, but was just a bit of fun. I may develop this character further and create a 3D rig for animated short.
Below is a copy of the initial sketch and some quick colour tests.
