The Mysterious Benedict Society

I've been reading this book over the past few days and I've been loving it! And this art is really good as well! I was wondering if I would be allowed to use part of this drawing as my twitter icon? (Reynie specifically) I would give you credit. But I will only use this as an icon if you're okay with it. Thanks for making wonderful art for a book that doesn't seem to have any recognition! Have a wonderful day.
