Seeing as The Fall takes a very prominent place in every Sherlockian's heart, I adored this piece amongst all your other Sherlock episode pieces. The use of Sherlock and John's hands, reaching out, on both the bottom and top suggests that the events of the Reichenbach Fall are what is between them, between the man on the ledge of St. Bart's and the man on the ground. Moriarty's bit is very evocative, and was done with plenty of attention to detail and lovely perspective. I love how you used the scene with John and Sherlock on either side of the fence, handcuffed together. That scene is in the midst of the drama of Sherlock's identity being ripped apart, and I just can't get over this piece. Well done.
Black and white were perfect for this mood. I love the red apple in the center, drawing our focus in. This looks like a very emotive noir. Flailing hand? Waving goodbye? It's been two years since Sherlock left our screens, but it's still too soon! Series 3 can't come soon enough. (But while we're waiting…more?)
And the texture on that cape. You've got quite the eye for cloth!
You should add your signature to your drawings... I've been sharing these amazing covers for the episodes in facebook, asking everybody if they knew the artist... until I found your deviantart account, thank God. That is my only critic, I love how accurate are these covers!
