Whuuu, this is beautiful! I ADORE how insane Jim looks. But I think maybe you should have left out Sherlock's hand on Jim's shoulder. I mean, the fact that Sherlock is even listening to him (you completely nailed his expression, btw) says enough about the kind of relationship these two have. Also, there's something funny about the placement of Sherlock's hand. He could not actually position his arm like that, they're too close together, Jim's right arm and chest would be in the way. But other than this, amazing work, I love it!!
I loved your Severus' drawings when I saw them some time ago, but now I've discovered that you have some Sherlock's ones too and their really wonderful. I hope you draw more about this fandom, I'd love you to.
Very well done. Nice and creepy.
