Let me tell ya, this is one of the hardest sonas I drew so far. This guy is so complicated, oh my goodness. Wings are always a problem to me, he has one tail that changes style midway, what a freaking challenge!
I learned I know nothing about pokemon anatomy. It took me more than 2h just to sketch this guy and for 45 minutes, he just looked like a generic fox! Was my eye style the problem? His hips wasn't big enough? Turned out I totally forgot Lucario have this tentacle hair thing! Not getting the Lucario feel was driving me insane, let me tell ya.

Well, I finally found a way to make fur popout without much difficulty! The tail and neck fur looks pretty great. I like how the shadows on the wings gave it some depth but the patterns on it doesn't quite follow it though. In the end, I like the final result.
