Well actually the 3 month gap happened because I just lost the impetus to keep drawing. I mostly felt that I had some obligation to keep, so I really just drew things in an attempt to get views, not because I necessarily enjoyed. I have a whole graveyard of unfinished projects that I totally lost interest in.
As for the perfecting of the art style, it was mostly due to taking a step back and seeing just what had already been done by other artists, and really just trying to find something completely unique. For example; Fluttershy pics number in the tens of thousands, now a large amount of them are practically the same thing, just with slightly tweaked styles. What I intended to do was be more selective about what I drew and just put a great deal more effort into each, so that at least some of my pics would stand out more than say; the hundredth picture of Fluttershy in a meadow (or something of that ilk).
Hopes this helps
