Writing a sequel

I had planned, even from the start when I had just begun writing my first fan fic, to have a sequel written for it. A sequel where the Mane Six and the ponified Sherlock Holmes face the wrath of the evil Professor and try to bring him and his vast criminal empire down. A more action-packed sequel but still retaining the elements of a detective story... perhaps like Guy Ritchie's "A Game of Shadows" (which, by the way, the idea of my sequel is greatly inspired by). Where our main characters and everything they've got within their power go against those of the Professors's, with an ending where we are unsure if heroes won or not.
But with summer's end and the return of school, I may not tend to this story like how I did to its predecessor. So, to those who liked Pinkie's Cupcakes and interested to the concept in which I had just presented, expect the Mane Six and Pony Sherlock Holmes vs. The Professor(that is the sequel's crude title that gives main concept) to come out in perhaps a couple months' time.
In the mean time, to inform you that I'm still active in this site, I shall post blogs about my thoughts of FiM's lore and musical compositions that fit certain characters from it. Anyways, for now, Au Revoir!
