Wow, that's a tough question; of course I've had inspiration for my style, but there's also a natural evolution to it and practice. It happens to all artists, if you see my drawing style now it is very different from this piece for example, not only because my inspiration changed, but also because I kept practicing different things for improvement, trying some new others and that also adds up to the natural evolution in ones style and skill. I think an important part of inspiration is to be limitless, I used to and still do have a wide range of artists I like, from classic ones, to realism, cartoon, american comics and anime that come from different artists  from different places and I supose that makes my style a little more expanded instead of limited to one taste/category/artist only. 

I hope this is a good answer? I really didn't knew what exactly you were looking for, but hope it helps
