WOW, I love this!! This is absolutely awesome.I'm very impressed, it's amazing.I do particularly like the "grunge-iness" of your interpretation of Sherlock, although for a completely different reason. X-) I don't believe Sherlock has all his cards on the table at all, but rather he's the one with the most to hide. Sherlock has Asperger's... and I believe the only ones who know about it aside from him are Mycroft and John... and it alienates him. Being an incredibly brilliant and intelligent detective is all he has going for him, it's all he has to feel good about himself in a life-long world of harassment and bullying for being so "different," so he's hanging onto it for dear life. That's why he flaunts it the way he does as a way to keep people from knowing. He puts on that ruse of a prideful and stone-faced attitude in order to scare people off of finding out what he truly is... autistic, insecure, and afraid. So I think the grunge look is perfect for him because it's exactly fitting of what he's doing, stoically intimidating people into keeping their distance lest they come close enough to see the truth. I think Mycroft also puts on an intimidating facade, but for a different reason. He's definitely not autistic, and he has a level of self-confidence and self-assurance that Sherlock never could, so I think he puts on that shifty piousness to keep anyone from getting so close to him that he may lose any control or influence he has in his associations with them. Though Sherlock and Mycroft are very different, as brothers they come from the same place, so it's easy to seem them developing the same tactics to deal with their very different issues.
