I haven't read the stories yet, so I don't know if there's a connection, but this has a very "Wolfwalkers" stylistic vibe to me. I have zero expertise in art, so I can't comment on technique or anything, but it looks really good to me. The only thing that bugged me is a "you can't unsee it" bit of personal stupidity once something popped into my head. The background color (maybe due to my colorblindness) looks fairly skin tone, and the way it darkens at the edges could make it look rounded. Add to that the way the wolf's bedding looks white and curly, and it looks like he's nested down in an old guy's chest hair.

Sorry. Good job on it though.
