I laughed too 'cos I've held conversations with sock puppets before. No joke. I was little, but still. Much fun.
Your lineart still continues to rock my socks. It's so clean and just looks good. Also, the expression on your face is perfect. You seem concerned and really want to know if you're insane. You're not, trust me.
And I wouldn't be so hard on your celshading. I never work with lighting sources on my work but that doesn't mean you can't shade and you did well with that, especially in the neck fur and back main. Such a perty picture.
