Badass! All the way around, Brian. Great approach. He remindes me a bit of a Brit/Victorian version of Charles Muntz from UP.
This is awesome. I love the anatomy and the dog is an especially nice touch, very cool.
There is nothing better than a dog in a matching outfit!! The pose on walter works well too, I like the balance of weight you used. I can see a subtle lean forward in his legs offset by the lean back in his upper body. Nice Brian!
