When I was asking for help for my Porcupine pic - http://www.furaffinity.net/view/10844895/ I asked to multiple artist to give me their point of view. One of them was Kats Tsilaa - http://xaadaas.deviantart.com/gallery/ - which, of course, he asked me with some resources and critiques on the formline pic. For his help I told him I could make a sumi-e drawing for him and he request me to draw him "carving" since it was his job. So here's him helping to an eagle (We both share it as Family crest) to get his wing. Care to mention the NWP art isn't traditional and never meant to and I don't do Formline for commissions (only Sumi-e).

Inks and watercolors over canson paper

Only meant to be used by me and Kats.
