Impressive art. I thought, when I first looked at this, that it was a reference to the story "A Study in Emerald" by Neil Gaiman--given the tentacles (you would understand had you read the story and knew both the works of Doyle and those of H.P Lovecraft).
I'm awed by the style of this sketch,
but most of all, I love how clockwork Watson and stoned squid Holmes show the dual nature which anyone (much less H/W) would have to posess in Victorian & Edwardian society -
and that even their deconstructed evil bits of psyche are stuck on eachother... I feel all warm and fuzzy.
